hi there  
I want to run a single test case so I read a document about testing  
and I found this command.

```auto
gradle test -Dtests.class=org.elasticsearch.package.ClassName

```

I want to test this class `NumberFieldMapperTests`  
so I executed command like this.

```auto
gradle test -Dtests.class=org.elasticsearch.index.mapper.NumberFieldMapperTests

```

But I met an error!  
Here is an error message

```auto
* What went wrong:
Execution failed for task ':test:framework:test'.
> There were no executed tests: 0 suites, 0 tests

* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':test:framework:test'.
at org.gradle.api.internal.tasks.execution.ExecuteActionsTaskExecuter.executeActions(ExecuteActionsTaskExecuter.java:98)

...

Caused by: : There were no executed tests: 0 suites, 0 tests
        at com.carrotsearch.ant.tasks.junit4.JUnit4.execute(JUnit4.java:1093)
...

```

please, help me

You have to run `gradle :core:test -Dtests.class=org.elasticsearch.index.mapper.NumberField` (note `test` -\> `:core:test`); when you run the top-level `test` task it will run `test` for all sub-projects. Since there are no test classes that match `org.elasticsearch.index.mapper.NumberFieldMapperTests` and we fail tests if no tests are executed, this is why you see the failure that you se.
