How to pass command line arguments to tests with gradle test?
提问by Oleksandr
I am using gradle to run JUnit tests. The problem is that I need to pass arguments from the command line to tests. I tries to pass System properties but failed.
我正在使用 gradle 运行 JUnit 测试。问题是我需要将参数从命令行传递给测试。我尝试传递系统属性但失败了。
gradle test -Darg1=something
Here is my test:
这是我的测试:
public class MyTest {
@Test
public void someTest() throws Exception {
assertEquals(System.getProperty("arg1"), "something");
}
}
It fails because there is no arg1
argument.
Is it possible somehow to pass command line arguments?
它失败了,因为没有arg1
争论。是否有可能以某种方式传递命令行参数?

When you run gradle test -Darg1=smth
, you pass system parameter arg1
to the Gradle JVM, not the test JVM where tests are run. It is designed this way to protect tests from side effects.
运行时gradle test -Darg1=smth
,您将系统参数传递arg1
给 Gradle JVM,而不是运行测试的测试 JVM。它的设计方式是为了保护测试免受副作用的影响。
If you need to propagate parameters to tests, use something like this
如果您需要将参数传播到测试,请使用类似这样的方法
test {
systemProperty 'arg1', System.getProperty('arg1')
}
and run it the same way.
并以同样的方式运行它。

Use -D to send your parameters in. Like so:
使用 -D 发送您的参数。像这样:
./gradlew test -Dgrails.env=dev -D<yourVarName>=<yourValue>
See the gradle command line documentationof -D.
请参阅-D的gradle 命令行文档。
To access it in the tests, you need to propagate it in your build.gradle file.
要在测试中访问它,您需要在 build.gradle 文件中传播它。
test {
systemProperty "propertyName", "propertyValue"
}
You can also pass all System Properties like so:
您还可以像这样传递所有系统属性:
test {
systemProperties(System.getProperties())
}
