Testing Java code with Groovy under Intellij: unable to resolve class GroovyTestCase
提问by Patrick Collins
I need to write a short test for some Java code. I used CTRL+SHIFT+T to generate one with IntelliJ, and selected "Groovy JUnit" as the testing library, then wrote the following test:
我需要为一些 Java 代码编写一个简短的测试。我用 CTRL+SHIFT+T 用 IntelliJ 生成一个，并选择了“Groovy JUnit”作为测试库，然后编写了以下测试：
package util
class FibonacciHeapTest extends GroovyTestCase {
FibonacciHeap<Integer> heap
void setUp() {
super.setUp()
heap = new FibonacciHeap<>()
}
void testAddInOrder() {
testForItems 1..1000
}
private void testForItems(Range<Integer> items) {
items.each {heap << it}
assertEquals heap.size, items.to
items.each {assertEquals heap.remove(), it}
}
}
However, when I right click on the test case in the project window, I don't get the "Run All Tests" option that I normally do with JUnit tests, and the compiler throws the following error:
但是，当我在项目窗口中右键单击测试用例时，我没有得到通常对 JUnit 测试执行的“运行所有测试”选项，并且编译器抛出以下错误：
Information:2/4/15 8:15 PM - Compilation completed with 2 errors and 0 warnings in 2 sec
/home/patrick/IdeaProjects/hackerrank/src/test/java/util/FibonacciHeapTest.groovy
Error:(3, 1) Groovyc: unable to resolve class util.FibonacciHeap
Error:(9, 1) Groovyc: unable to resolve class GroovyTestCase
Trying to import GroovyTestCaseor FibonacciHeapmanually causes the same error. IntelliJ does not add any import statements when I let autocomplete finish the names for me, like it usually would with Java code.
尝试导入GroovyTestCase或FibonacciHeap手动会导致相同的错误。当我让自动完成为我完成名称时，IntelliJ 不会添加任何导入语句，就像通常使用 Java 代码一样。
What am I doing wrong?
我究竟做错了什么？

You have to configure Groovy SDK first. See the screenshot

This worked for me :
这对我有用：
- Open Gradle window (on right side in my case)
- Click on refresh button
- Done
- 打开 Gradle 窗口（在我的情况下位于右侧）
- 点击刷新按钮
- 完毕

I had a similar problem with creating test classes in IntelliJ, and it was solved when creating a new directory outside of the com.company folder (where I had the class I wanted to test).
我在 IntelliJ 中创建测试类时遇到了类似的问题，并且在 com.company 文件夹（我有我想测试的类）之外创建一个新目录时解决了这个问题。
- Create a new directory for the test classes on the same level as your src folder
- Right click on your new test directory, and "Mark directory as" --> "Test Resources Root"
- Now create a test class, which should automatically be added to your test directory.
- 为与 src 文件夹相同级别的测试类创建一个新目录
- 右键单击您的新测试目录，然后“将目录标记为”-->“测试资源根目录”
- 现在创建一个测试类，它应该会自动添加到您的测试目录中。

In my case, what I did to resolve the issue was rather simple.
就我而言，我为解决问题所做的工作相当简单。
- Close IntelliJ
- Open the attached homepage...
- Remove your project by clicking on the
xthen... - Click on
Import Project, Navigate to thebuild.graddlefile of your project and open.
- 关闭 IntelliJ
- 打开附带的主页...
- 通过单击
x然后删除您的项目... - 单击
Import Project，导航到build.graddle项目文件并打开。
That was it and all the Red highlightings disappeared.
就是这样，所有红色突出显示都消失了。

Build -> Rebuild project in the IDE itself (as opposed to maven, in my case) did it for me.
Build -> 在 IDE 本身中重建项目（在我的例子中与 maven 相反）为我做了这件事。

As @sman591 pointed out in a comment, if you are getting the error:
正如@sman591 在评论中指出的那样，如果您收到错误消息：
groovyc: unable to resolve class groovy.util.GroovyTestCase
and you already have groovy as a dependency then you are probably just missing the junit dependency.
并且您已经将 groovy 作为依赖项，那么您可能只是缺少 junit 依赖项。

In IntelliJ IDEA I re-imported the project. It worked then.
I closed idea. I removed .ideafolder in the project. And I imported the project.
在 IntelliJ IDEA 中，我重新导入了该项目。它当时起作用了。我关闭了想法。我删除.idea了项目中的文件夹。我导入了项目。
Then I needed to set up Groovy, see previous answers, mark test directory as test source in all modules of my project.
然后我需要设置 Groovy，查看以前的答案，在我的项目的所有模块中将测试目录标记为测试源。
