Won't this run tests twice? about scoverage-maven-samples HOT 7 CLOSED

@gslowikowski wondering if you might be able to help me out. i tried to follow what you were saying over in the closed ticket i reffed above but im still getting 2 runs of test if i turn of all scoverage i dont get a report... so im kinda confused as to why you said to disable all tasks for scoverage in the pom.xml

Hi @babineaum

Sorry for not responding for some time.

IMPORTANT!
When I'm writing about (not) adding scoverage tasks to pom.xml file I'm thinking about build section, not reporting. In short, reporting is OK.

Generally, I never add scoverage tasks to my poms (build section).
If I want coverage check, I run something like this mvn clean package scoverage:check.
If I want coverage report - mvn scoverage:report
If report must be added to Maven site, it has to be added to reporting section, like in the line you cited above.
If you run e.g. mvn test scoverage:check or mvn test scoverage:report the tests will run twice, once on uninstrumented classes (in test task) and second time on instrumented classes (in test task executed in lifecycle forked by scoverage:report task)

The issue scoverage/scoverage-maven-plugin#39 was about forking scoverage lifecycle from already forked scoverage lifecycle. It is possible, but does not make sense.

Hmmm ok well i seem to have the same problem as the other person "ghost".

I guess my question is, is there a way to run a 'mvn clean install' and have the build create an artifact that I can deploy and also run instrumented tests without running the non instrumented tests as well?

Edit: I'll note that I am getting two runs of the tests, one pre the scoverage fork during the test phase, by scalattest-maven-plugin and the other during the scoverage fork when scoverage calls scalatest-maven-plugin and runs tests after instrumentation.

You need two Maven calls, for example:

• mvn clean install -DskipTests
• mvn scoverage:report

There is no way (IMO) to set and clear skipTests flag interpreted by Surefire plugin depending on the context (scoverage or not).

For me single mvn clean process-classes scoverage:report command works. proccess-classes generates classed dir under target so I can run my application. I don't attach any scoverage goal to build lifecycle in pom configuration.

@gslowikowski
mvn clean package scoverage:check
still runs the build and tests twice. Is there a way to run the build and tests just once (similar to what JaCoCo does for Java) ?

There is a way to avoid running tests twice now. Check this issue scoverage/scoverage-maven-plugin#61 please.
