unit-testing - Grails的正确Spock语法是什么？

Question

我正在运行Grails 2.5.0应用程序，并且执行以下测试:

package moduleextractor

import grails.test.mixin.TestFor
import spock.lang.Specification

/**
 * See the API for {@link grails.test.mixin.web.ControllerUnitTestMixin} for usage instructions
 */
@TestFor(ExtractorController)
class ExtractorControllerSpec extends Specification {

    def moduleDataService
    def mockFile

    def setup() {
        moduleDataService = Mock(ModuleDataService)
        mockFile = Mock(File)
    }

    def cleanup() {
    }

    void "calls the moduleDataService"() {
        given: 'a term is passed'
            params.termCode = termCode
        when: 'the getModuleData action is called'
            controller.getModuleData()
        then: 'the service is called 1 time'
            1 * moduleDataService.getDataFile(termCode, 'json') >> mockFile
        where:
            termCode = "201415"
    }
}

如果我运行grails test-app unit:spock，我会得到:

| Tests PASSED - view reports in /home/foo/Projects/moduleExtractor/target/test-reports

我不明白为什么会看到2个测试。我的BuildConfig文件中没有包含spock，因为Grails 2.5.0中已经包含了spock。另外，由于我还没有服务，因此该测试不应该通过。为什么会通过？

另外，当我运行此grails test-app ExtractorController时，我得到另一个结果:

| Running 2 unit tests...
| Running 2 unit tests... 1 of 2
| Failure:  calls the moduleDataService(moduleextractor.ExtractorControllerSpec)
|  Too few invocations for:
1 * moduleDataService.getDataFile(termCode, 'json') >> mockFile   (0 invocations)

    at org.spockframework.mock.runtime.MockController.leaveScope(MockController.java:76)
    at moduleextractor.ExtractorControllerSpec.calls the moduleDataService(ExtractorControllerSpec.groovy:27)
| Completed 1 unit test, 1 failed in 0m 3s
| Tests FAILED  - view reports in /home/foo/Projects/moduleExtractor/target/test-reports
| Error Forked Grails VM exited with error

如果我运行grails test-app unit:我得到:

| Running 4 unit tests...
| Running 4 unit tests... 1 of 4
| Failure:  calls the moduleDataService(moduleextractor.ExtractorControllerSpec)
|  Too few invocations for:
1 * moduleDataService.getDataFile(termCode, 'json') >> mockFile   (0 invocations)
Unmatched invocations (ordered by similarity):

    at org.spockframework.mock.runtime.MockController.leaveScope(MockController.java:76)
    at moduleextractor.ExtractorControllerSpec.calls the moduleDataService(ExtractorControllerSpec.groovy:27)
| Completed 1 unit test, 1 failed in 0m 3s
| Tests FAILED  - view reports in /home/foo/Projects/moduleExtractor/target/test-reports
| Error Forked Grails VM exited with error

首先有人可以告诉我运行spock测试的正确语法是什么？

另外，在命令中包含unit和unit:和unit:spock有什么区别？

(由于Spock随Grails 2.5.0一起提供，因此无论如何它将运行spocks测试。)

正确的语法是什么，为什么它看到2个测试而不是1个？

Answer 1

不必担心测试数量。对我来说从来都不是问题。您始终可以检查报告HTML文件，以查看确切的内容。

我总是与任何一个进行测试

grails test-app

要么

grails test-app ExtractorController

您得到的错误意味着您对测试进行了编码，以期望在调用controller.getModuleData()时使用参数null和'json'调用moduleDataService.getDataFile()。但是，从未调用moduleDataService.getDataFile()，因此测试失败。

Spock需要一些习惯。我建议查看Grails文档中的示例并阅读Spock Framework Reference。
