When is it appropriate to use the @TestVisible Annotation

I think the question in your title is too broad and opinion based to touch on here. I have worked with many developers who feel the annotation should never be used, but regardless, I have found some instances where it felt like the best option. For me, it boils down to using it only when I need to be able to control application behavior but want to avoid checking .

For your use case, let's take a moment to think about the behavior you actually care about. You want the function to toggle the selection of all of your users (I would rename it from select to toggle to reflect that purpose). So what you really care about is not this flag at all, but rather your collection of wrapper instances. That is what you should be asserting against. Make sure its size hasn't changed, and that the individual selections are correct.

Then again, if you take a step back and look at what you are trying to accomplish, do you really need to involve the server at all for this mechanism? It may be worth looking at how you can move the functionality wholesale to the client side, since it is not exactly complex logic where unit tests offer significant advantages over acceptance tests run by end users.


(Just an aside to show the one time I do find perfectly acceptable)

When writing trigger handlers, it is useful to use a static flag to turn the functionality off when running certain tests to reduce the cost of on that object. Granted, there are other strategies you can employ to reduce or remove the need to perform in the first place. But sometimes you can't, and making trigger execution cheaper to run can dramatically simplify/quicken your test suite.

Then, in some test where you don't actually care about the trigger, but need your records to exist in the database:

Introduction:


Testing(writing Unit tests) is an important part of the Salesforce Development Life Cycle. Before deploying the code developed into the production environment, Salesforce requires at least 75% of the code to be covered by our test classes. Salesforce has done that to make sure that our code doesn’t break in any situation in Production.

  • Unit tests are the developers’ tests to ensure that functionality is working as expected, considering Both positive & Negative tests.
  • Unit tests are also used in long-term development projects to ensure that project is running error-free & smooth.

Advantage of Unit Testing/Test Classes:

  • Ensuring that your Apex classes and triggers work as expected
  • Having a suite of regression tests that can be rerun every time classes and triggers are updated to ensure that future updates you make to your app don’t break existing functionality
  • Meeting the code coverage requirements for deploying Apex to production or distributing Apex to customers via packages.
  • High-quality apps delivered to the production org, which makes production users more productive
  • High-quality apps are delivered to package subscribers, which increases your customer’s trust.
  • Reduce the bug Cost
  • Perform Bulk tests

Annotations:

  • @isTest– used at the Class or Method level to indicate it only contains code that supports Test Coverage. Classes defined with this annotation do not count against your organization limit for Apex code.
  • @testSetup – used to indicate a method is specifically used to set up test data. When supplied, the @testSetup method is executed before any other methods in the test class. Each test method will have access to the original set of constructed test data regardless of how any other test method uses that data.
  • @testVisible –When constructing Apex logic, it makes sense to define members such as methods, variables, and inner classes as private or protected. Doing so, however, can make achieving Test Coverage more challenging. Fortunately, Salesforce has thought ahead and provided us with the @testVisible annotation.  Using this annotation on private or protected members allows test class access but still preserves the defined visibility to non-test classes.
  • @isTest(SeeAllData=True) –Ideally, your Salesforce test classes should be responsible for creating their own data. However, sometimes you need access to existing data, and using @isTest(SeeAllData=True) allows your test classes and test methods this access. Available as of API version 24.0, there are some caveats when using. “SeeAllData=True” can be used at the Class and Method level. When using “SeeAllData=True” at the Class level, all methods get access to existing data but using “SeeAllData=True” at just the Method level only allows those Methods access to existing data. Lastly, using “SeeAllData=False” at the Method level will not override “SeeAllData=True” used at the Class level.
  • @isTest(isParallel=true) — Use the @isTest(isParallel=true) annotation to indicate test classes that can run in parallel. Default limits on the number of concurrent tests do not apply to these test classes.

Methods used in Salesforce Test Classes:

Test.startTest() and Test.stopTest()

StartTest()  – Marks the point in your test code when your test actually begins. Use this method when you are testing governor limits.

public static Void startTest()

StopTest()  – Marks the point in your test code when your test ends. Use this method in conjunction with the startTest method.

public static Void stopTest()

  • The startTest method marks the point in your test code when your test actually begins. Each test method is allowed to call this method only once
  • All of the code before this method should be used to initialize variables, populate data structures, and so on, allowing you to set up everything you need to run your test. 
  • Any code that executes after the call to startTest and before stopTest is assigned a new set of governor limits.
  • The startTest method does not refresh the test context: it adds a context to your test. For example, if your class makes 98 SOQL queries before it calls startTest. The first significant statement after startTest is a DML statement. The program can now make an additional 100 queries. Once stopTest is called, however, the program goes back into the original context and can only make 2 additional SOQL queries before reaching the limit of 100
  • All asynchronous calls made after the startTest method are collected by the system. When stopTest is executed, all asynchronous processes are run synchronously

System.Assert:

It accepts two parameters: First one (mandatory) is the condition test and the second one is used to display a message in case the condition fails.Syntax: System.assert(var1 == var2,”msg”)

System.AssertEquals:

It accepts three parameters; the first two (mandatory) are the variables that will be tested for equality or inequality. The third (optional)one is used to display a message in case the condition fails.Syntax: System.assertEquals(var1, var2,”msg”);

System.runAs()

All Apex code runs in system mode, where the permissions and record sharing of the current user are not taken into account. The system method runAs enables us to write test methods that change the user context to an existing user or a new user so that the user’s record sharing is enforced. The runAs method doesn’t enforce user permissions or field-level permissions, only record sharing. The following items use the permissions granted by the user-specified with runAsrunning as a specific user: Dynamic Apex Methods using with sharing or without sharing

Shared records
The original permissions are reset after runAs completes.The runAs method ignores user license limits.

Test.isRunningTest()

The Test.isRunningTest()  method is used to identify if the piece of code being executed is invoked from a Test class execution or other artefacts such as a Trigger, Batch Job etc. Returns true if the code being executed is invoked from a test class otherwise, returns a false.
Example:
Performing web service callouts in Apex are not supported within Test Code. Hence we could use the Test.isRunningTest() to conditionally identify and route the execution of a code block that calls the Test Mock framework to simulate mock, callout response.

Test.loadData()

Using the Test.loadData method, you can populate data in your test methods without writing any code lines. Follow these steps:

  1. Add the data in a .csv file.
  2. Create a static resource for this file.
  3. Call Test.loadData within your test method and passing it the sObject type token and the static resource name.

For example, for Account records and a static resource name of , make the following call:

List<sObject> ls = Test.loadData(Account.sObjectType, 'myResource');

The Test.loadData method returns a list of sObjects that correspond to each record inserted.

You must create the static resource before calling this method. The static resource is a comma-delimited file ending with a .csv extension. The file contains field names and values for the test records. The first line of the file must contain the field names, and subsequent lines are the field values. To learn more about static resources, see “Defining Static Resources” in the Salesforce online help. Once you create a static resource for your .csv file, the static resource will be assigned a MIME type. Supported MIME types are:

  • text/csv
  • application/vnd.ms-excel
  • application/octet-stream
  • text/plain

Unit Tests to be Done for?

we have to write test classes for below items/components in salesforce.

  1. Apex Trigger
  2. Apex Class – Handler/Helper, WebService, Apex REST, SOAP
  3. VF Page
  4. Apex Batch/Queueable/Future Method

Best Practices & Notes of Salesforce Test Class:

1. Test class must start with @isTest annotation if the class version is more than 25
2. Test environment support @testVisible, @testSetUp as well
3. Unit test is to test a particular piece of code working properly or not.
4. Unit test method takes no argument, commits no data to database, sends no email, flagged with testMethod keyword.
5. To deploy to production, at-least 75% code coverage is required
6. System. Debug statements are not counted as a part of the apex code limit.
7. Test method and test classes are not counted as a part of code limit
9. We should not focus on the percentage of code coverage. We should make sure that every use case should be covered, including positive, negative, bulk, and single record.
Single Action -To verify that the single record produces the correct and expected result.
Bulk action -Any apex record trigger, class, or extension must be invoked for 1-200 records.
Positive behavior: Test every expected behavior that occurs through every expected permutation. The user filled out every correct data and did not go past the limit.
Negative Testcase:-Not to add future date, Not to specify a negative amount.
Restricted User:-Test whether a user with restricted access is used in your code.
10. Test class should be annotated with @isTest.
11. @isTest annotation with test method is equivalent to testMethod keyword.
12. Test method should static and no void return type.
13. Test class and method default access are private, no matter to add access specifier.
14. classes with @isTest annotation can’t be an interface or enum.
15. Test method code can’t be invoked by non-test request.
16. Stating with salesforce API 28.0 test method can not reside inside non-test classes.
17. @Testvisible annotation to make visible private methods inside test classes.
18. Test method can not be used to test web-service call out. Please use call-out mock.
19. You can’t send emails from the test method.
20.User, profile, organization, AsyncApexjob, Corntrigger, RecordType, ApexClass, ApexComponent ,ApexPage we can access without (seeAllData=true) .
21. SeeAllData=true will not work for API 23 version eailer .
22. Accessing static resource test records in test class e,g List<Account> accList=Test.loadData(Account,SobjectType,’ResourceName’).
23. Create TestFactory class with @isTest annotation to exclude from organization code size limit.
24. @testSetup creates test records once in a method and is used in every test class test method.
25. We can run unit tests by using Salesforce Standard UI,Force.com IDE, Console, API.
26. The Maximum number of test classes run per 24 hours the period is not greater than 500 or 10 multiplication of test classes of your organization.
27. As apex runs in system mode, the permission and record sharing are not taken into account. So we need to use system.runAs to enforce record sharing.
28. System.runAs will not enforce user permission or field level permission.
29. Every test to runAs count against the total number of DML issued in the process

In this post we will talk about Apex Test class best practices in Salesforce with examples. Please check our Deep Drive in Test classes session recording here. If you are new to Test classes. Please check this post to learn about test classes in Salesforce with examples.

What to Test in Apex?

Unit tests are the test performed by the developers to ensure that functionality is working as expected considering Both positive & Negative tests. We should not focus on the percentage of code coverage. Salesforce recommends the following components need to tested.

  1. Single Records: This includes testing to verify that a single record produces the correct, expected result
  2. Bulk Records: Any apex code, whether a triggers, a class or on extension may be used for 1 to 200 records we must test not only the single record case, but the bulk cases as well.
  3. Positive scenarios: This type of component testing expect a system to save a record without error.
  4. Negative scenarios: This type of component testing expect a system to give error.
  5. Restricted User: Test whether a user with restricted access to the objects used in code sees the expected behavior, i.e whether they can run the code or receive error messages.

Best Practices of Test Classes in Apex

To write an effective test cases, a developer needs to ensure to include the below points into the test class

  • Test class must start with @isTest annotation.
  • Focus 90+ : To deploy to production at least 75% code coverage is required. But always try to focus on 90%+. We should not focus on the percentage of code coverage, We should make sure that every use case should covered including positive, negative,bulk and single record.
  • One Assert Statement per method : Always put assert statements for negative and positive tests.
    • System.assert(condition, msg)
    • System.assertEquals(expected, actual, msg)
    • System.assertNotEquals(expected, actual, msg)
  • @testSetup to create test records once in a method and use in every test method in the test class.
  • Create TestFactory class with @isTest annotation to exclude from organization code size limit.
  • No SeeAllData=true : Always use ( seeAllData = false ) at class or method level. User, profile, organization, AsyncApexjob, Corntrigger, RecordType, ApexClass, ApexComponent, ApexPage we can access without (seeAllData=true) .
  • As apex runs in system mode so the permission and record sharing are not taken into account . So we need to use System.runAs to enforce record sharing.
  • Avoid Using Hard Coding Ids anywhere in test Class or any apex class
  • Governor limits : Using gives developers a new set of governor limits for the act stage of their test. then allows them to return to their previous governor limits. Test classes must test for Governor Limits using Limits Class
  • Testing Exception : Any exceptions that are caught in the production methods should be tested by feeding the test data that throws exception. Exception Type and error message should be asserted
  • Exercise bulk trigger functionality – use at least 200 records in your tests

How to Create Test Data

Let see how we can create the test data for test classes in Salesforce.

1) Manually create it for each test


To create a test method we can use testMethod keyword or @isTest annotation

  • Pro: Variables in context
  • Con: Lots of duplicate code

2) Load data via CSV Static Resource


We can use Test.loadData method to create test data in our test class.

  • Pro: Don’t need to make code updates for record creation
  • Con: Might be harder to track changes to static resources

3) Test Setup (@TestSetup)


We can create one createTestData method with @TestSetup annotation

  • Pro: Reduce repetitive code
  • Con: Variables out of context

4) Test Factory


Here is example of test data factory in Salesforce.

  • Pro: Single location to update schema in code
  • Con: Variables out of context

Consideration

Test classes did not commit the data which is created in test method so you don’t need to delete the test data which is created in test classes. Let see some more consideration in details.

Important thing to learn
  • Test method and test classes are not counted as a part of code limit
  • System.debug statement are not counted as a part of apex code limit.
  • @isTest annotation with test method  is equivalent to testMethod keyword.
  • Test class and method default access is private, no matter to add access specifier.
  • Classes with @isTest annotation can’t be a interface or enum.
  • Test method code can’t be invoked by non test request .

  • You can’t  send email from test method.
  • SeeAllData=true will not work for API 23 version eailer.
  • We can run unit test by using Salesforce Standard UI,Force.com IDE ,Console ,API.
  • System.runAs will not enforce user permission or field level permission .
  • Every test to runAs count against the total number of DML issued in the process .
  • Test environment support @testVisible, @testSetup as well
  • Test method should static and no void return type.
  • Accessing static resource test records in test class e,g List accList=Test.loadData(Account,SobjectType,’ResourceName’).

Apex Test, Best Practices

Salesforce Test Automation

@TestVisible 

Use the TestVisible annotation to allow test methods to access private or protected members of another class outside the test class. These members include methods, member variables, and inner classes. This annotation enables a more permissive access level for running tests only. This annotation doesn’t change the visibility of members if accessed by non-test classes.

Example 

public class TestVisibleExample { // Private member variable @TestVisible private static Integer recordNumber = 1; // Private method @TestVisible private static void updateRecord(String name) { // Do something } }

This is the test class that uses the previous class. It contains the test method that accesses the annotated member variable and method.
@isTest private class TestVisibleExampleTest { @isTest static void test1() { // Access private variable annotated with TestVisible Integer i = TestVisibleExample.recordNumber; System.assertEquals(1, i); // Access private method annotated with TestVisible TestVisibleExample.updateRecord('RecordName'); // Perform some verification } }

TestSetup Annotation



Methods defined with the @testSetup annotation are used for creating common test records that are available for all test methods in the class.
@testSetup static void methodName() { }


https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_classes_annotation_testsetup.htm


IsTest Annotation


Use the @isTest annotation to define classes and methods that only contain code used for testing your application. [email protected] annotation on methods is equivalent to the testMethod keyword. The @isTest annotation can take multiple modifiers within parentheses and separated by blanks.​​​​​​​
@isTest private class MyTestClass { // Methods for testing @isTest static void test1() { // Implement test code } @isTest static void test2() { // Implement test code } }
https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_classes_annotation_isTest.htm​​​​​​​

Test visible salesforce

 

What is @TestVisible annotation?

@TestVisible annotation allows test methods to access private or protected members of the apex class. These members can be methods, variables or inner classes. @TestVisible annotation enables a more permissive access level for running tests only. This annotation doesn’t impact the visibility of members if accessed by non-test classes. When you use this annotation, you don’t have to change the access modifiers of your methods and the member variable to the public while accessing them in a test method.

For Example:

This example shows how to access private class member variable and private method with help of @TestVisible annotation.
public class TestVisibleClass { // Private member variable @TestVisible private static Integer recordCount = 1; // Private method @TestVisible private static void updateAccount(String name) { // Do something } } This is the test class that uses the previous class. It contains the test method that accesses the @TestVisible annotated private member variable and method
@isTest private class TestVisibleClassTest { @isTest static void testExample() { // Access private variable annotated with TestVisible Integer i = TestVisibleClass.recordCount; System.assertEquals(1, i); // Access private method annotated with TestVisible TestVisibleClass.updateAccount('Someone'); // Perform some verification } }

Apex Test Class Best Practices

What is a Test Method?

Once an Apex class is written, it must pass through a unit test, which verifies whether a particular piece of code or function is working properly or not, before it is deployed. Also, at least 75% of our apex code must be covered in order to successfully deploy the code to the production organization. Unit tests are written in Apex Code and annotated with the testMethod keyword.

E.g.: Static testMethod void methodname()

Use of @isTest annotation
This annotation defines a class as a test class that contains code for testing our application and these classes are not counted against our organization limit of apex code. Classes annotated with @isTest can be declared as private or public.

E.g.:

@isTest Private class ExampleTest { Static testmethod void test1() { // Your code } }

Use of @TestVisible annotation
It allows to access private or protected members (methods, variables, and inner classes) and of another class outside the current test class. Here, we don’t need to compromise with access modifiers for the sake of code coverage. We just need to append @TestVisible notation before any private or protected member of a class.

E.g.:

Public class TestVisibleExample { @TestVisible private static Integer recordNumber = 1; @TestVisible private static void updateRecord(String name) {} }

Use of IsTest(SeeAllData=true) Annotation
This annotation grants access to all data in the organization, and it is available for Apex code saved using Salesforce API version 24.0 and later, but as a best practice, it is recommended not to use this annotation unless there is a unique need.

E.g.: PriceBook creation (sObjects that doesn’t allow DML operation), so, here, we can use this annotation to get pre-existing data stored in the organization.

Use of System.runAs() method
Normally, all Apex codes run in System mode, and therefore the current user’s various permissions and record sharing rules are not taken into consideration. The system method, System.runAs(),lets us write test methods that change user contexts to either an existing user or a new user. All of that user’s record sharing is then enforced. You can only use runAs in a test method. But runAs() does not validate CRUD or Field Level Security permissions.

Use of Test.isRunningTest() method
There may be some cases where we cannot test a piece of code in normal manner. In those cases, use Test.isRunningTest() in your code to identify that context of class is Test or not.

E.g.: We can generate fake response easily, while testing web services.

Use of System.Assert/System.AssertEquals Methods
These methods are used to ensure that the Apex code executes and returns the expected value.
System.Assert: It accepts two parameter: First one (mandatory) is the condition to test and the second one is used to display a message in case the condition fails.
Syntax: System.assert(var1 == var2,”msg”)
System.AssertEquals: It accepts three parameters; the first two (mandatory) are the variables that will be tested for equality or inequality, and the third (optional) one is used to display a message in case the condition fails. Syntax: System.assertEquals(var1, var2,”msg”);

Use of Test.startTest/Test.stopTest method
Test.startTest and Test.stopTest, are used when testing governor limits. When you call Test.startTest method, you will get a fresh set of governor limits for the remainder of the test until you call Test.stopTest, and each test method is allowed to call this method only once.

Test methods will no longer be able to compile in a non-test class
Now starting with the Summer ’13 release, you will not able to compile test method in the same class as your regular executable code. Apex test method need to be created in a separate class (A “test class” is one marked with the @isTest annotation), and these changes will be applicable for new classes written in v28.0 and above.

Avoid Hardcoding IDs
Never hard code ids of any sObjects inside test method, but if a Constant needs to be asserted, then make use of Constant class or Custom Labels or Custom Settings because hard coding strings in unit tests may result in test failure when things like Pick list values change.

Summary
Following Apex test class best practices is vital to ensure the quality of the code and also it simplifies the regression testing.
