A test case without assertions ensures only that no exceptions are thrown. Beyond basic runnability, it ensures nothing about the behavior of the code under test.
This rule raises an exception when no assertions from any of the following frameworks are found in a test:
org.springframework.test.web.servlet.ResultActions.andExpect()
@Test public void testDoSomething() { // Noncompliant MyClass myClass = new MyClass(); myClass.doSomething(); }
@Test public void testDoSomething() { MyClass myClass = new MyClass(); assertNull(myClass.doSomething()); // JUnit assertion assertThat(myClass.doSomething()).isNull(); // Fest assertion }
