Find ignored unit tests which are correct - java

I have big project and many ignored unit tests. Is there any way that I can run all ignored tests using surefire maven plugin and see list of passed tests?
Total number of ignored tests are >1000, so, manually it is impossible.

Will gradle run Tests annotated with #NotThreadSafe run as a single test process at a time

We have currently set up our application set up with Junit 4 and Maven with the surefire plugin.
Now we are migrating to gradle and we want to run the test case in parallel with the exception of the ones annotated with #NotThreadSafe. Given the long running nature of our test cases it is hard to find out if they are running in parallel or not.
Has anybody used the #NotThreadSafe annotation together with gradle?
In the gradle docs I wasn't able to find out if it is supported or not.

Sonar false overall coverage (jacoco)

I'm running Jacoco and Sonar on multimodule Java8 project.
I have unit tests in each of the modules and to save resources I collect all 'integration tests' into one "integration-tests-runner" and run them all there (wrapping them with before and after tests).
When measuring coverage UT generates exec file per module target/jacoco-ut.exec, while the IT generates one exec file: /target/jacoco-it.exec.
When I run sonar I reuse those exec files, giving path to the jacoco-it.exec.
I get a very weird image:
How can it be that overall coverage is lower?
I found the problem and the solution.
From Sonar website I see this:
By default, when no coverage report is found, the JaCoCo plugin will
not set any value for coverage metric. This behaviour can be
overriden to force coverage to 0% in case of a lack of report by
setting the following property :
sonar.jacoco.reportMissing.force.zero=true
This means that UT analysis was skipped for modules without any tests.
Since I've set the sonar.jacoco.itReportPath from parent pom then all modules got analyzed for integration tests coverage, and overall coverage.
Bottom line: setting the property sonar.jacoco.reportMissing.force.zero=true from parent pom fixed the numbers.
Why is that weird? The unit and integration tests execute code and certain executed code chunks overlap. With other words, the code which is covered by the unit and integration tests is not disjoint, thus you cannot simply add them up.

Is there an equivalent of junit test suite in Scala

In Java, you can create a junit test suites and put all your junit test cases in it. This allows you to run all your test cases all at once and get the testing results immediately (e.g. how many tests passsed and failed, and which tests failed). Is there something equivalent in Scala within the ScalaTest?
Thanks
I don't know if there's anything equivalent for ScalaTest but in general this is a bad idea. It requires you to keep your test suite class up to date when you add new tests. Both your IDE and your build tool should let you be able to automatically discover and run all tests at once.
If you're using maven or gradle, just placing all your tests under the src/test/scala directory should be enough that running the test target will execute all test

How can I run all JUnit tests in one package # NetBeans?

I have like trillion test packages with bazillion tests and I want to run just some of packages. Now I must run whole project (some tests takes long to complete) or I need to run every single file manually. How is possible to run just some packages in NetBeans ? I can't find this option ...
It's probably not what you want, but the NetBeans help topic, Running a JUnit Test, says:
If you want to run a subset of the
project's tests or run the tests in a
specific order, you can create test
suites that specify the tests to run
as part of that suite. After creating
a test suite you run the suite in the
same way you run a single test class.
Creating a test suite is covered in the topic Creating a JUnit Test.
If you use JUnit 4 then try ClasspathSuite and its regex filters.

How to run integration tests?

In our project, we have a plenty of unit tests. They help to keep project rather well-tested.
Besides them, we have a set of tests which are unit tests but depends on some kind of external resource. We call them external tests. For example, they can sometimes access web-services.
While unit tests are easy to run, the integrational tests couldn't pass sometimes: for example, due to timeout error. Also, these tests can take too much time to run.
Currently, we keep integration/external unit tests just to run them when developing corresponding functionality.
For plain unit tests, we use TeamCity for continuous integration.
How do you run the integration unit tests and when do you run them?
In our project we have separate suite for regular/plain unit tests and separate suite for integration tests. The are two reasons for that:
performance: integration tests are much slower,
test fragility: integration tests fail more often due to environment-related conditions (give false positives).
We use TeamCity as our main Continuous Integration server and Maven as build system. We use the following algorithm to run the tests:
We run unit tests at within Eclipse IDE and before every commit.
We run unit tests automatically after each commit on TeamCity agents using Maven's mvn clean install
We run integration tests automatically on TeamCity agent after "main" build is completed.
The way we trigger integration tests execution is by configuring TeamCity's integration.tests task to be dependent on "main" continous.build task, see here for details: http://confluence.jetbrains.net/display/TCD4/Dependencies+Triggers
We run only integration tests (excluding unit tests) by:
using separate directory named
"src/it/java" to keep integration
tests,
excluding by default this source folder from maven-surefire-plugin configuration (configuration/excludes element),
using Maven profile called "integration" to exclude regular unit tests and include tests from "src/it/java" (this profile is configured by passing -Pintegration in integration.tests task).
We're using Maven2: maven-surefire-plugin to run unit tests (in the test phase) and maven-failsafe-plugin for integration tests (integration-test phase).
By default, all tests run when the project is built, however integration tests can be turned off using profiles.
In many cases integration tests are the part of the module, n some cases there are also dedicated modules which only do integration tests.
One of the teams also uses Fitnesse for acceptance testing. These tests are also in dedicated modules.
We're using Hudson for CI.
We run all the tests in one huge suite. It takes 7 minutes to run.
Our integration tests create mock servers. They never time out -- except when the test requires the server to time out.
So we have the following kinds of things. (The code sample is Python)
class SomeIntegrationTest( unittest.TestCase ):
def setUp( self ):
testclient.StartVendorMockServer( 18000 ) # port number
self.connection = applicationLibrary.connect( 'localhost', 18000 )
def test_should_do_this( self ):
self.connection.this()
self.assert...
def tearDown( self ):
testClient.KillVendorMockServer( 18000 )
This has some limitations -- it's always forking the client mock server for each test. Sometimes that's okay, and sometimes that's too much starting and stopping.
We also have the following kinds of things
class SomeIntegrationTest( unittest.TestCase ):
def setUp( self ):
self.connection = applicationLibrary.connect( 'localhost', 18000 )
def test_should_do_this( self ):
self.connection.this()
self.assert...
if __name__ == "__main__":
testclient.StartVendorMockServer( 18000 ) # port number
result= unittest.TextTestRunner().run()
testclient.KillVendorMockServer( 18000 )
system.exit( result.failures + result.errors )
To support this testing, we have a number of mocked-up servers for various kinds of integration tests.
We use Jenkins to run our tests automatically.
Be careful of differencing between Unit and Integration - Tests. It is confusing to talk about "Integration Unit Tests"
Maven offers good support to distinguish between Unit and Integration Tests-
Failsafe & Surefire Plugin.
From Apache Maven Project:
The Failsafe Plugin is designed to run integration tests while the Surefire Plugin is designed to run unit tests.
(see: http://maven.apache.org/surefire/maven-failsafe-plugin/)
You need to configure these Plugins in your pom.xml
You then only use mvn test - to run unit tests or mvn verify to run integration tests.
Unit test should run periodically f.i. every 15 min.
Integration Test, normally take long, and should run f.i. every 24 hours.
Hope that helps others.
