Let's add an annotation of our own, where we run a class only if a certain Java system property is set. The Method Annotation, we'll define a simple annotation that targets the method level and defines the system property that must be set for that test method to run: @Target( thod ) @Retention(ntime) public @interface SystemPropertyCondition / The name of. Parameterized Tests, the example used throughout this tutorial is about writing a simple number range counter, which delivers a certain amount of consecutive integers, starting from a given value. Additionally a counter depends on a storage type for preserving its current state.
Java - junit custom runner implementation - Stack Overflow
There is nothing wrong with this approach, but it's a bit heavy handed for the simplest of cases. In these simple situations it's easier to just keep the integration tests in the src/test/java directory and run them along with all your other tests. Type and thod and, in your test runner, evaluate not only tAnnotations but also getTestClass.getAnnotations. It's not difficult to add extra annotation types that check for things like Host OS, environment variables or an open TCP port on localhost. However the structuring capabilities of suites are somewhat limited. Because of this JUnit 4.8 introduced the lesser known Categories concept. This makes it possible to define custom category types like unit-, integration- and acceptance tests for example. Since I have already published an introduction to JUnit Rules, I decided to skip the announced sections on that topic. Instead I spend the latter a minor update. Test Runners Architecture, dont be afraid to give up the good to go for the great. To assign a test case or a method to one of those categories the Category annotation is provided: / definition of the available categories public interface Unit public interface Integration public interface Acceptance / category assignment of a test case @Category(ass) public class NumberRangeCounterTest.
