First, you need to create the test utility class. The TestDataFactory class is a special type of class—it is a public class that is annotated with isTest and can be accessed only from a running test. Test utility classes contain methods that can be called by test methods to perform useful tasks, such as setting up test data. This test utility class contains one static method, createAccountsWithOppswhich accepts the number of accounts held in the numAccts parameter and the number of related opportunities to create for each account held in the numOppsPerAcct parameter.

The first loop in the method creates the specified number of accounts and stores them in the accts list variable. After the first loop, the insert DML statement is called to create all accounts in the list in the database. The second loop creates the opportunities.

Because each group of opportunities are linked to one account, the outer loop iterates through accounts and contains a nested loop that creates related opportunities for the current account. The next time the nested loop is run, opportunities are added to the same list using the add method.

Opportunities are linked to their parent accounts using the AccountId field.

Next, the insert DML statement is efficiently called outside the loop to create all opportunities in the collection for all accounts in one call only. The array returned by the TestDataFactory. One test method is not enough to test all the possible inputs for the trigger.

We need to test some other conditions, such as when an account without opportunities is deleted. We also need to test the same scenarios with a bulk number of records instead of just a single record.

Here is an updated version of the test class that contains the three additional test methods. Save this updated version of the class. The final step is to run the test methods in our test class, now that the class contains more comprehensive tests and has been refactored to use a test data factory. Learning Objectives After completing this unit, you'll be able to: Create a test utility class.

Use a test utility method to set up test data for various test cases. Execute all test methods in a class. Create Test Data for Apex Tests Use test utility classes to add reusable methods for test data setup. Replace the default class body with the following.

Testing for Different Conditions One test method is not enough to test all the possible inputs for the trigger. Running All Test Methods The final step is to run the test methods in our test class, now that the class contains more comprehensive tests and has been refactored to use a test data factory.

To execute the same test run, click the Tests tab, select your test run, and then click Test Rerun. Check the results in the Tests tab by expanding the latest test run. The test run should report that all four tests passed!Testing is the integrated part of Apex or any other application development. In Apex, we have separate test classes to develop for all the unit testing. This code coverage is performed by the test classes.

Test classes are the code snippets which test the functionality of other Apex class. Let us write a test class for one of our codes which we have written previously. We will write test class to cover our Trigger and Helper class code. Below is the trigger and helper class which needs to be covered. We need to create data for test class in our test class itself. By using this annotation, you declared that this is a test class and it will not be counted against the organization's total code limit.

Unit test methods are the methods which do not take arguments, commit no data to the database, send no emails, and are declared with the testMethod keyword or the isTest annotation in the method definition.

Also, test methods must be defined in test classes, that is, classes annotated with isTest. These are the standard test methods which are available for test classes.

These methods contain the event or action for which we will be simulating our test. Like in this example, we will test our trigger and helper class to simulate the fire trigger by updating the records as we have done to start and stop block.

This also provides separate governor limit to the code which is in start and stop block. This method checks the desired output with the actual.

In this case, we are expecting an Invoice record to be inserted so we added assert to check the same. Apex - Testing Advertisements. Previous Page.

Test Setup method in Apex

Is that the right way? Yes, you must re-query the data. Sometimes you might use constant strings to pull in, for instance a custom setting:. Often, this approach is used for configuration data that will be common to your tests, be it in a Custom Object or Custom Setting. It is a correct way. I would, however, like to identify few benefits of testSetup below.

Absolutely missed the custom setting thing, even though I did it myself after knowing how useful it was to create custom settings in testSetup and then check them every testmethod of my test class. I would, however, like to identify few benefits of testSetup below Use this annotation if you want to create test data once and use it in all test methods of your class.

Therefore, you don't need to recreate the data again. Records created in a test setup method are rolled back at the end of test class execution. You may have multiple testSetup methods in your class, however, their execution order is not guaranteed. See also: Test Setup Method Considerations Test setup methods are supported only with the default data isolation mode for a test class.

You can have only one test setup method per test class. If a test setup method calls a non-test method of another class, no code coverage is calculated for the non-test method.

Also, because the rollback of records that are created during test setup happens at the end of the execution of the entire class, the number of records that are rolled back is reduced.

As a result, system resources are used more efficiently compared to creating those records and having them rolled back for each test method. If a test class contains a test setup method, the testing framework executes the test setup method first, before any test method in the class. Records that are created in a test setup method are available to all test methods in the test class and are rolled back at the end of test class execution.

If a test method changes those records, such as record field updates or record deletions, those changes are rolled back after each test method finishes execution. The next executing test method gets access to the original unmodified state of those records. Test setup methods are defined in a test class, take no arguments, and return no value. The following is the syntax of a test setup method.

The following example shows how to create test records once and then access them in multiple test methods. Also, the example shows how changes that are made in the first test method are rolled back and are not available to the second test method.
