Test.isRunningTest()
Test.isRunningTest() This is not used in test classes but in other
classes in order to verify if the call is from a test class.
When we are setting up test data from Apex test method, we need a way to
disable the triggers that will fire. It might cause "LimitException:
"Too many SOQL queries: 101". In this case, the triggers
are not the target of the test case, hence this scenario will cause the test
method to fail
Setup up the trigger by leveraging isRunningTest(). isRunningTest() -
Returns true if the currently executing code was called by code contained in a
test method, false otherwise. Use this method if you need to run different code
depending on whether it was being called from a test.
if(Test.isRunningTest()){
//do something
}
Other Usage scenarios
1. To ensure the trigger doesn't execute the batch if
Test.IsRunningTest() is true, and then test the batch class with it's own test
method.
2. Testing callouts - in your callout code you check to see if you're
executing within a unit test context by checking Test.isRunningTest() and
instead of getting your callout response from an HttpResponse.send() request,
you return a pre-built test string instead.
