What happens when a test setup method fails?
If a fatal error occurs during the execution of a test setup method, such as an exception that’s caused by a DML operation or an assertion failure, the entire test class fails, and no further tests in the class are executed. If a test setup method calls a non-test method of another class, no code coverage is calculated for the non-test method.
Can you have more than one test setup method?
You can have only one test setup method per test class. If a fatal error occurs during the execution of a test setup method, such as an exception that’s caused by a DML operation or an assertion failure, the entire test class fails, and no further tests in the class are executed.
How to separate setup and non setup objects?
System.runAs ( new User (Id = UserInfo.getUserId ()) ) { …your setup-object DML… } If you need to do this in a non test scenario @future, Batch Apex, apex:actionFunction or something as simple as user button flow, it can be used to separate the transactions.
Which is an example of a test setup method?
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.
What happens when you change a test method?
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.
Can you write a test for a method that deletes?
Yes, this test looks like it is written rigidly, but that’s really all you’re testing in the unit test, anyways. You want the DB to fetch a Person from the database using an argument, hence why there are two Person objects, and you expect to delete that passed Person object, which is why you expect the call. Simple method yields simple test.
