Spring Boot - My unit tests are being skipped

Question

I am migrating an existing project to boot. I created a brand new project using start.spring.io and copied over the source code, etc. Everything compiles, but when I do a 'mvn test' it compiles the classes but then only executes the default 'ApplicationTests' (created by start.spring.io).

Here's an excerpt from the maven output:

    [INFO] --- maven-resources-plugin:2.6:testResources (default-testResources) @ pendview ---
    [INFO] Using 'UTF-8' encoding to copy filtered resources.
    [INFO] skip non existing resourceDirectory C:\dev\pendview2\src\test\resources
    [INFO]
    [INFO] --- maven-compiler-plugin:3.1:testCompile (default-testCompile) @ pendview ---
    [INFO] Changes detected - recompiling the module!
    [INFO] Compiling 26 source files to C:\dev\pendview2\target\test-classes
    [INFO]
    [INFO] --- maven-surefire-plugin:2.15:test (default-test) @ pendview ---
    [INFO] ------------------------------------------------------------------------
    [INFO] BUILD SUCCESS
    [INFO] ------------------------------------------------------------------------

What's even stranger is that if I pass '-Dtest=TestAuthController' then it does run that specific unit test:

    [INFO] --- maven-compiler-plugin:3.1:testCompile (default-testCompile) @ pendview ---
    [INFO] Changes detected - recompiling the module!
    [INFO] Compiling 26 source files to C:\dev\pendview2\target\test-classes
    [INFO]
    [INFO] --- maven-surefire-plugin:2.15:test (default-test) @ pendview ---
    [INFO] Surefire report directory: C:\dev\pendview2\target\surefire-reports

    (skipped output of AuthControllerTest for brevity)

    -------------------------------------------------------
     T E S T S
    -------------------------------------------------------Results :

    Tests run: 6, Failures: 0, Errors: 0, Skipped: 0

What am I doing wrong? Does spring boot setup a surefire config that I'm not conforming to?

Any help would be greatly appreciated! -Trey

Answer 1

Spring Boot configures the Surefire plugin to run all test classes that have a name ending with Test or Tests but not starting with Abstract. You can see this configuration in the spring-boot-starter-parent pom. If your test class is named TestAuthController then it doesn't match this configuration. Renaming it to AuthControllerTest or AuthControllerTests should fix your problem.

Answer 2

Seems for me there is some issue with Maven surefire plugin, when it doesn't detect tests, if your test class name doesn't end with Tests suffix. :-)
