AssertionMode

AssertionMode is used to detect and warn a developer that a test does not execute any assertions. It is usually the case that if a test function does not execute some kind of assertion then the test is probably erroneous (see note). It is common to see junior developers write a test that does not actually test anything.

Therefore by setting AssertionMode to Error or Warn, the lack of assertions in a test will cause the test to fail, or a warning to be outputted respectively.

The default value of None is the status quo - absense of assertions will cause no issues.

Note: There are valid use cases for not having an assertion. For example, testing that some code will compile is a valid use case, and the successful return of the compiler is sufficient test.
