Assertions are comments that do not become outdated. They document which theoretical states are intended, and which states should not occur. If code is changed so states allowed change, the developer is soon informed and needs to update the assertion.
You can use assertEqualsCanonicalizing method which was added in PHPUnit 7.5. If you compare the arrays using this method, these arrays will be sorted by PHPUnit arrays comparator itself. Code example: class ArraysTest extends \PHPUnit\Framework\TestCase { public function testEquality() { $obj1 = $this->getObject(1); $obj2 = $this->getObject(2); $obj3 = $this->getObject(3); $array1 = [$obj1, $obj2, $obj3]; $array2 … Read more
No, there’s nothing wrong with assert as long as you use it as intended. That is, it’s supposed to be for catching cases that “can’t happen”, during debugging, as opposed to normal error handling. Assert: A failure in the program’s logic itself. Error Handling: An erroneous input or system state not due to a bug … Read more
If you add in Hamcrest and JUnit4, you could do: String x = “foo bar”; Assert.assertThat(x, CoreMatchers.containsString(“foo”)); With some static imports, it looks a lot better: assertThat(x, containsString(“foo”)); The static imports needed would be: import static org.hamcrest.MatcherAssert.assertThat; import static org.hamcrest.CoreMatchers.containsString;
You can use issubclass() like this assert issubclass(suit, Suit).
The old method (of JUnit 3) was to mark the test-classes by extending junit.framework.TestCase. That inherited junit.framework.Assert itself and your test class gained the ability to call the assert methods this way. Since version 4 of JUnit, the framework uses Annotations for marking tests. So you no longer need to extend TestCase. But that means, … Read more
I’ve needed this several times as well. I’ve put together a small sample below, which you’d want to adjust to your needs. Basically, you create your own Appender and add it to the logger you want. If you’d want to collect everything, the root logger is a good place to start, but you can use … Read more
assert will terminate the program (usually with a message quoting the assert statement) if its argument turns out to be false. It’s commonly used during debugging to make the program fail more obviously if an unexpected condition occurs. For example: assert(length >= 0); // die if length is negative. You can also add a more … Read more
There is no standard assert in JavaScript itself. Perhaps you’re using some library that provides one; for instance, if you’re using Node.js, perhaps you’re using the assertion module. (Browsers and other environments that offer a console implementing the Console API provide console.assert.) The usual meaning of an assert function is to throw an error if … Read more
<?php require_once ‘PHPUnit/Framework.php’; class ExceptionTest extends PHPUnit_Framework_TestCase { public function testException() { $this->expectException(InvalidArgumentException::class); // or for PHPUnit < 5.2 // $this->setExpectedException(InvalidArgumentException::class); //…and then add your test code that generates the exception exampleMethod($anInvalidArgument); } } expectException() PHPUnit documentation PHPUnit author article provides detailed explanation on testing exceptions best practices.
