A colorful BDD-style test runner for Java
Spectrum is inspired by the behavior-driven testing frameworks Jasmine and RSpec, bringing their expressive syntax and functional style to Java tests. It is a custom runner for JUnit, so it works with many development and reporting tools out of the box.
Spectrum 1.2.0 is available as a package on JCenter and Maven Central.
Spectrum supports Specification-style tests similar to RSpec and Jasmine:
@RunWith(Spectrum.class)
public class Specs {{
describe("A list", () -> {
List<String> list = new ArrayList<>();
afterEach(list::clear);
it("should be empty by default", () -> {
assertThat(list.size(), is(0));
});
it("should be able to add items", () -> {
list.add("foo");
list.add("bar");
assertThat(list, contains("foo", "bar"));
});
});
}}And also Gherkin-style tests similar to Cucumber:
@RunWith(Spectrum.class)
public class Features {{
feature("Lists", () -> {
scenario("adding items", () -> {
Variable<List<String>> list = new Variable<>();
given("an empty list", () -> {
list.set(new ArrayList<>());
});
when("you add the item 'foo'", () -> {
list.get().add("foo");
});
and("you add the item 'bar'", () -> {
list.get().add("bar");
});
then("it contains both foo and bar", () -> {
assertThat(list.get(), contains("foo", "bar"));
});
});
});
