Why is this an issue?

Shared naming conventions allow teams to collaborate efficiently. This rule raises an issue when a test method name does not match the provided regular expression.

Noncompliant code example

With the default value: ^test[A-Z][a-zA-Z0-9]*$

@Test
public void foo() {  // Noncompliant
  //...
}

Compliant solution

@Test
public void testFoo() {
  // ...
}
