Write a parameterized test for my email validator using a list of valid and invalid strings.

java-junit

Agent

I'll create a @ParameterizedTest for you. I'll use @ValueSource to provide the email strings and then implement the test method to assert that your validator returns the expected boolean result. I'll also use @DisplayName to make the test results easy to read in your IDE.
