Write Java JUnit tests in Jasmine style
Latest commit 337d778 Feb 22, 2016 @mscharhag Updated readme



Oleaster allows you to write JUnit tests like you would write Jasmine tests.

An Oleaster JUnit test looks like this:

public class OleasterIntroductionTest {{
    describe("A suite", () -> {
        it("contains a spec with an expectation", () -> {
            expect(40 + 2).toEqual(42);

Oleaster consists out of two independent libraries:

The Oleaster JUnit Runner gives you the option to write JUnit tests in the format shown above. Java 8 Lambda expressions are used to structure a test in suites and specifications.

Oleaster-Matcher provides Jasmine-like Matchers (expect(..).toEqual(..)) to validate test results. These Matchers can be used as a replacement (or extension) for standard JUnit assertions.

Oleaster tests are (mostly) written with Oleaster (see: Oleaster JUnit Runner Tests and Oleaster Matcher Tests).
