Assertions (by way of the assert keyword) were added in Java 1.4. They are used to verify the correctness of an invariant in the code. They should never be triggered in production code, and are indicative of a bug or misuse of a code path. They can be activated at run-time by way of the … Read more
It’s easier to do this: driver.findElements(By.linkText(“myLinkText”)).size() < 1
Best thing one can do until something is implemented in the library is to use Xunit.SkippableFact: [SkippableFact] public void SomeTest() { var canRunTest = CheckSomething(); Skip.IfNot(canRunTest); // Normal test code } This will at least make it show up as a yellow ignored test case in the list.

assertions are, in theory, for testing invariants, assumptions that must be true in order for the code to complete properly. The example shown is testing for valid input, which isn’t a typical usage for an assertion because it is, generally, user supplied. Assertions aren’t generally used in production code because there is an overhead and … Read more
http://apigen.juzna.cz/doc/sebastianbergmann/phpunit/function-assertInstanceOf.html I think you are using this function wrong. Try: $this->assertInstanceOf(‘User’, $user);
Empty lists/dicts evaluate to False, so self.assertTrue(d) gets the job done.
Using JUnit 4.4 you can use assertThat() together with the Hamcrest code (don’t worry, it’s shipped with JUnit, no need for an extra .jar) to produce complex self-describing asserts including ones that operate on collections: import static org.junit.Assert.assertThat; import static org.junit.matchers.JUnitMatchers.*; import static org.hamcrest.CoreMatchers.*; List<String> l = Arrays.asList(“foo”, “bar”); assertThat(l, hasItems(“foo”, “bar”)); assertThat(l, not(hasItem((String) null))); … Read more
As you mention that you use Hamcrest, So I would pick one of the collection Matchers import static org.hamcrest.collection.IsIterableContainingInAnyOrder.containsInAnyOrder; import static org.junit.Assert.assertThat; public class CompareListTest { @Test public void compareList() { List<String> expected = Arrays.asList(“String A”, “String B”); List<String> actual = Arrays.asList(“String B”, “String A”); assertThat(“List equality without order”, actual, containsInAnyOrder(expected.toArray())); } }
You can use the assert_raises assertion, or the must_raise expectation. it “must raise” do assert_raises RuntimeError do bar.do_it end -> { bar.do_it }.must_raise RuntimeError lambda { bar.do_it }.must_raise RuntimeError proc { bar.do_it }.must_raise RuntimeError end If you need to test something on the error object, you can get it from the assertion or expectation like … Read more
99.9% likely that you have corrupted memory (over- or under-flowed a buffer, wrote to a pointer after it was freed, called free twice on the same pointer, etc.) Run your code under Valgrind to see where your program did something incorrect.
