Test two different scheduled apex classes from one test class

Question

I have two different scheduled classes that I am trying to schedule from a single test class. A simplification is the first class creates a set of records, and then the second class does something else with those records.

I can write a test class for either of them, but since they are so closely linked I thought it would be good to create a single test class that tests them both.

First When I scheduled the job with String jobId = System.schedule('ScheduledApexTest',CRON_EXP, new exampleClass()); and then stop the test with Test.stopTest();, nothing happens. The TimesTriggered stays 0. This is kind of a separate issue, but I've been testing using the method below.

test.startTest();

SchedulableContext sc;
exampleClass1 EC1 = new exampleClass1();
EC.execute(sc);

SchedulableContext sc2;
exampleClass2 EC2 = new exampleClass2();
EC2.execute(sc2);

test.stopTest();

For some reason when I do this, it seems to run exampleClass1 twice and doesn't run exampleClass2. I also tried using only one schedulablecontext in both calls, but that gives a similar error.

Each of them works by themselves, but it acts weird when I do both together. Is this something that can be done, or do I just have to do this in two different test classes?

Answer 1

You can really only test one asynchronous thing per unit test. Use two unit tests. Both unit test methods can be in the same class, and you can use @TestSetup if you want to set up data common to both tests in order to preserve execution time/governor limits. If you do decide to use @TestSetup, keep also in mind that @TestSetup will eat up your unit test governor limits unless you call Test.startTest() first, so make sure you do that.
