JUnit - How to test a method with different values?
提问by user722781
I have a method and wish to test it with different values. My question is: how can I write a JUnit test that would test the same method with different values?
我有一个方法并希望用不同的值来测试它。我的问题是：如何编写一个 JUnit 测试来测试具有不同值的相同方法？

You can take a look at parametrized tests like in example.
您可以查看示例中的参数化测试。
You can also use theorieswhich is more convenient in a lot of cases.

JUnit4 supports parameterized tests for just this purpose.
JUnit4 仅为此目的支持参数化测试。
See this tutorial.

I suggest you create a different unit test for each one of your (overloaded) function definitions, because arguably you are testing in fact different functions. For instance:
我建议您为每个（重载的）函数定义创建一个不同的单元测试，因为可以说您实际上正在测试不同的函数。例如：
class MainClass {
public void method( int param) {... }
public void method( String param) { ...}
}
class MainClassTest {
@Test
public void methodIntTest() {
//call method(int)
}
@Test
public void methodStringTest() {
//call method(String)
}
}
