Scala's sbt has the option to run only tests that previously failed. Is there a gradle equivalent?
https://www.scala-sbt.org/1.x/docs/Testing.html#testQuick
gradle does this automatically with all update-to-date tests marked as such, based on code changes since latest test passing.
You can also force re-run of tests if need be: How to run Gradle test when all tests are UP-TO-DATE?

Is there a way to have SBT re-run only the tests that have failed in the last run of the test suite? For example, if I run sbt test and 3 out of the 20 tests I run fail, is there any command I can run to have SBT just re-run those 3 tests that fail?
Specifically I am using Scala Test and Scala Check for the tests I am running through SBT.
If you are using the latest version of sbt simply run sbt testQuick.

I am trying to merge two modules into single module. Both are successfully running modules. I merge two modules. And trying to run the test cases.
i am compiling source and testcases by using sbt commands:
sbt
clean
compile
project module-read
test:compile
it:test
Till test:compile everything working fine but after it:test, it showing lot of compilation issues.
Could I know best way of compiling?
The test:compile task will only compile tests within the src/test/scala folder as per the default sbt test configuration.
In order to compile your integration tests (in src/it/scala) you will have to run it:compile .
See http://www.scala-sbt.org/0.13.5/docs/Detailed-Topics/Testing.html#integration-tests for more info.
I have not found any documentation on how to do this. For JUnit the equivalent would be:
mvn -Dtest=org.apache.spark.streaming.InputStreamSuite test
tl;dr mvn test -Dsuites="some.package.SpecsClass"
I found an answer from here and it works:(https://groups.google.com/forum/#!topic/scalatest-users/Rr0gy61dg-0)
run test 'a pending test' in HelloSuite, and all tests in HelloWordSpec:
mvn test -Dsuites='org.example.
HelloSuite #a pending test, org.example.HelloWordSpec'
run all tests in HelloSuite containing 'hello':
mvn test -Dsuites='org.example.HelloSuite hello'
for more details: http://scalatest.org/user_guide/using_the_scalatest_maven_plugin
Found the answer: it is
-DwildcardSuites
So here is the example command line:
mvn -pl streaming -DwildcardSuites=org.apache.spark.streaming.InputStreamSuite test
Update Newer versions of scalatest use
-Dsuites
So the syntax would be:
mvn -pl streaming -Dsuites=org.apache.spark.streaming.InputStreamSuite test
Note that if you have some Java tests in the same module, as much of spark does, you need to turn them off -which you can do by telling surefire to run a test that isn't there
Here is the test that I've just been running
mvn test -Dtest=moo -DwildcardSuites=org.apache.spark.deploy.yarn.ClientSuite
That skips the java test and only runs the scala one.
One thing which scalatest doesn't seem to do is let you run a single test within a suite, the way maven surefire does. That's not ideal if you have one failing test in a big suite.
[Correction 2016-08-22: looks like you can ask for a specific suite by name; look at the other answers below. Happy to be wrong].
Is there a way to build tests with SBT without running them?
My own use case is to run static analysis on the test code by using a scalac plugin. Another possible use case is to run some or all of the test code using a separate runner than the one built into SBT.
Ideally there would be a solution to this problem that applies to any SBT project. For example, Maven has a test-compile command that can be used just to compile the tests without running them. It would be great if SBT had the same thing.
Less ideal, but still very helpful, would be solutions that involve modifying the project's build files.
Just use the Test / compile command.
Test/compile works for compiling your unit tests.
To compile integration tests you can use IntegrationTest/compile.
Another hint to continuously compile on every file change: ~Test/compile
We have a build.sbt file that is used for multiple projects. Doing sbt test:compile compiled the tests for every single project and took over 30 minutes.
I found out I can compile only the tests for a specific project named xyz by doing:
sbt xyz/test:compile
Using sbt version 1.5.0 and higher test:compile returns deprecation warning.
Use Test / compile.

I have an SBT 0.7.5 project and its some test cases fail. Until all test cases are fixed, I want to skip tests to generate a JAR. Is there any command line argument that tells SBT to skip all tests, like Maven's -Dmaven.test.skip=true flag?
I had the same problem, I'm using the assembly plugin. In this case, the solution was to modify the build file and add
test in assembly := {}
Instead of using compile, you could use package. The compile tasks also runs the tests, package doesn't.
