Inspectopedia 2025.2 Help

Message missing on assertion

Reports calls to assertXXX() or fail() without an error message string argument. An error message on assertion failure may help clarify the test case's intent.

Example:

assertTrue(checkValid());

After the quick-fix is applied:

assertTrue(checkValid(), "|");

The message argument is added before or after the existing arguments according to the assertions framework that you use.
