groovy.lang.MissingPropertyException: No such property: b for class: a

[kerby82]

I'm trying to test a groovy file that referentiate a class on another groovy file

vars/a.groovy

def runMigrations {
 if (b.getBoolean('xxxx)) {
  return true
 }
}

If I create a test like:

class ATests extends BasePipelineTest {
 void setUp() throws Exception[
  super.setUp()
  def a = loadScript('vars/a.groovy')
 }

@Test
 void runMig() {
  a.runMigrations()
  printCallStack()
 }
}

I got an error saying: groovy.lang.MissingPropertyException: No such property: b for class: a

[nre-ableton]

The error seems legit. Where does b come from anyways? I suspect you need to share a bit more context of a.groovy.

both a.groovy and b.groovy are located in vars This is my build.gradle.kts

plugins {
  id("com.mkobit.jenkins.pipelines.shared-library") version "0.10.1"

}

I'm testing the framework so b.groovy is just

def getBoolean(String input) {
 return true
}

How do the test framework should load implicitly the b class?

[kerby82]

The main issue here how can a groovy file referentiating a method from another groovy file be tested?

[nre-ableton]

Ah, ok, I see what you mean now. So first of all, your build.gradle file doesn't matter, at least when Jenkins is concerned. Instead, you'll need to create a new instance of b and attach it to the script instance in your test cases, like so:

class ATests extends BasePipelineTest {
  Object a
  Object b

  @Override
  @Before
  void setUp() {
    super.setUp()
    this.a = loadScript('vars/a.groovy')
    this.b = loadScript('vars/b.groovy')
  }

  @Test
  void runMig() {
    a.b = this.b
    a.runMigrations()
    printCallStack()
  }
}

Thanks @nre-ableton: That helped me a lot!
