[C-JVM]Using datatables in groovy step definitions

[rsilva4]

I can't find anything about this in the Groovy examples. Here what I
have tried:

Given(~'^the following external datasources:$') { eds ->

def listEds = eds.asList(ExternalDataSource)
listEds.each {
print it
ExternalDataSource.create(it);
}
assert ExternalDataSource.all().size() == listEds.size()
}

That outputs:

| Running 1 cucumber test...
org.codehaus.groovy.runtime.InvokerInvocationException:
groovy.lang.MissingMethodException: No signature of method:
net.inductiva.collector.ExternalDataSource.create() is applicable for
argument types: (net.inductiva.collector.ExternalDataSource) values:
[net.inductiva.collector.ExternalDataSource : null]
Possible solutions: create(), merge(), read(java.io.Serializable),
count(), delete(), ident()

'print it' prints nothing, and trying to debug (using eclipse STS)
does not stop at the breakpoints.

Here is an example:

It looks like you're doing everything right.

I managed to sucessufully test with the datatable:

Given(~'^the following external datasources:$') { eds ->

def listEds = eds.asList(ExternalDataSource)

listEds.each { ExternalDataSource it ->
it.save()
}
assert ExternalDataSource.findAll().size() == listEds.size()
}

However, I still don't have a clue how to debug or print stuff in the
step definitions.

Are you saying that `println("HELLO")` at the top of your step
definition prints nothing??

Exactly. Your phrasing lead to an experiment:

import groovy.time.TimeCategory;

import cucumber.table.DataTable;

import net.inductiva.collector.ExternalDataSource;

this.metaClass.mixin (cucumber.runtime.groovy.EN)

println("HELLO")

Given(~'^the following external datasources:$') { eds ->

println("HELLO Inside Given")

}

OUTPUT:

| Server running. Browse to http://localhost:8080/collector

HELLO

| Running 1 cucumber test...

| Completed 1 cucumber test, 0 failed in 581ms

The print inside the step it's not visible.

How do you know the step definition gets executed?
Is the output inside Eclipse's "console" window?
Can you see it if you run it all from outside eclipse (Maven, Ant,
whatever you're using)?

In IntelliJ, clicking on various nodes in the JUnit "tree" will
show/hide output so that only what was printed during a certain test
(scenario) is shown.
I'm not sure if Eclipse behaves the same, but it might. Try selecting
the root element.

Yes the output inside Eclipse's "console" window. 

Just tried using grails command from shell directly same result. 

Can it be something related with my logging configuration? It seams unlikely since the first print runs. I know that my step runs because if I include some invalid assertion it fails, p.e.: assert false.

I don't get the Junit tree in eclipse because Cucumber tests are not seen like Junit tests. 

To use cucumber-jvm I follow this instructions https://github.com/hauner/grails-cucumber/wiki/Testing-Grails-with-Cucumber-and-Geb which results in adding this dependencies to my project:

../plugins/cucumber-0.2.3/lib/cucumber-core-1.0.0.RC21-SNAPSHOT.jar

../plugins/cucumber-0.2.3/lib/cucumber-groovy-1.0.0.RC21-SNAPSHOT.jar

../plugins/cucumber-0.2.3/lib/cucumber-html-0.2.1.jar

../plugins/cucumber-0.2.3/lib/gherkin-2.9.0.jar

Reading this https://github.com/hauner/grails-cucumber/blob/master/CHANGES.md we can realize that with the current release cucumber-jvm is embedded in the plugin, something to change in the next release where it will fetch cucumber-jvm as a dependency and move on to 1.0.2 version.

"Currently the plugin registers the cucumber test type only to the functional test phase." can be read in the plugin page, so no unit tests

They are if you kick it off with JUnit:
https://github.com/cucumber/cucumber-jvm/blob/master/groovy/src/test/java/cucumber/runtime/groovy/RunCukesTest.java
I assume you're using the CLI runner then.

Maybe you have run into the same issue as this?

Ok, we can track the why about not printing stuff here: https://github.com/hauner/grails-cucumber/issues/4

Thanks Aslak for all your attention
