AssertContains on strings in jUnit
提问by ripper234
Is there a nicer way to write in jUnit
有没有更好的方法在 jUnit 中编写
String x = "foo bar";
Assert.assertTrue(x.contains("foo"));

If you add in Hamcrest and JUnit4, you could do:
如果添加 Hamcrest 和 JUnit4，则可以执行以下操作：
String x = "foo bar";
Assert.assertThat(x, CoreMatchers.containsString("foo"));
With some static imports, it looks a lot better:
使用一些静态导入，它看起来好多了：
assertThat(x, containsString("foo"));
The static imports needed would be:
所需的静态导入是：
import static org.junit.Assert.assertThat;
import static org.hamcrest.CoreMatchers.containsString;

use fest assert 2.0whenever possible EDIT: assertjmay have more assertions (a fork)
尽可能使用fest assert 2.0编辑：assertj可能有更多断言（一个叉子）
assertThat(x).contains("foo");

Use hamcrest Matcher containsString()
使用 hamcrest Matcher containsString()
// Hamcrest assertion
assertThat(person.getName(), containsString("myName"));
// Error Message
java.lang.AssertionError:
Expected: a string containing "myName"
got: "some other name"
You can optional add an even more detail error message.
您可以选择添加更详细的错误消息。
// Hamcrest assertion with custom error message
assertThat("my error message", person.getName(), containsString("myName"));
// Error Message
java.lang.AssertionError: my error message
Expected: a string containing "myName"
got: "some other name"

Another variant is
另一种变体是
Assert.assertThat(actual, new Matches(expectedRegex));
Moreover in org.mockito.internal.matchersthere are some other interesting matchers, like StartWith, Containsetc.
此外，在org.mockito.internal.matchers有一些其他有趣的匹配，比如StartWith，Contains等等。

I've tried out many answers on this page, none really worked:
我在这个页面上尝试了很多答案，但没有一个真正有效：
- org.hamcrest.CoreMatchers.containsStringdoes not compile, cannot resolve method.
- JUnitMatchers.containsStringis depricated (and refers to CoreMatchers.containsString).
- org.hamcrest.Matchers.containsString: NoSuchMethodError
- org.hamcrest.CoreMatchers.containsString无法编译，无法解析方法。
- JUnitMatchers.containsString已弃用（并引用CoreMatchers.containsString）。
- org.hamcrest.Matchers.containsString: NoSuchMethodError
So instead of writing readable code, I decided to use the simple and workable approach mentioned in the question instead.
因此，我决定使用问题中提到的简单可行的方法，而不是编写可读的代码。
Hopefully another solution will come up.
希望另一个解决方案会出现。

It's too late, but just to update I got it done with below syntax
为时已晚，但只是为了更新我使用以下语法完成了
import org.hamcrest.core.StringContains;
import org.junit.Assert;
Assert.assertThat("this contains test", StringContains.containsString("test"));

assertj variant
assertj 变体
import org.assertj.core.api.Assertions;
Assertions.assertThat(actualStr).contains(subStr);
