测试执行期间出错

Question

所有测试执行日志都包含以下错误：

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':test'.
> No tests found for given includes: [my.packege.TestclassSpec]

使用命令：test-app。

运行测试

如果使用JUnit运行相同的测试，一切都好。

如何在日志中避免此错误？

UPDATE 考试类：

class TestclassSpec  extends GebSpec {

def setup() {
}

def cleanup() {
}

void "test title"() {
    when:"The home page is visited"
        go '/'

    then:"The title is correct"
        title == "MyGame"
}
}

此外，如果仅运行测试方法，则出现下一个错误::

FAILURE: Build failed with an exception.

* What went wrong:
Task 'title' not found in root project
