Spock is a testing framework. You write tests in Groovy, which results in less code that is more readable. Good!
I first heard about Spock on Communities in Action and wanted to take it for a test ride. The problem was that I had some trouble getting started as the documentation seemed to be a bit outdated. Here’s a short summary of what I had to do.
The first obstacle was finding a binary download. I ended up grabbing one from their build server.
The next step is adding the spock-core-*.jar to your project and enable groovy support. (In Intellij I got a “dialog” in the top of my groovy file saying that I had to configure the Groovy SDK.)
Next up is adding a new test class and extend spock.lang.Specification. When the test is written, you can run it as a regular JUnit test.
Sweet!
Here’s a simple example
class GLMathTest extends Specification {
def "multiplying 4x4 matrix"() {
given:
float[] m1 = [
1, 0, 0, 0,
1, 1, 0, 0,
1, 0, 1, 0,
1, 0, 0, 1,
]
float[] m2 = [
1, 5, 9, 13,
2, 6, 10, 14,
3, 7, 11, 15,
4, 8, 12, 16
]
when:
float[] result = GLMath.multiply4x4(m1, m2)
then:
result == [
28, 5, 9, 13,
32, 6, 10, 14,
36, 7, 11, 15,
40, 8, 12, 16
]
}
}
