在JUnit中断言正则表达式匹配 [英] Assert regex matches in JUnit

问题描述

Ruby的 Test :: Unit 有一个很好的 assert_matches 方法，可用于单元测试以断言a正则表达式匹配一个字符串。

Ruby's Test::Unit has a nice assert_matches method that can be used in unit tests to assert that a regex matches a string.

JUnit中有这样的东西吗？目前，我这样做：

Is there anything like this in JUnit? Currently, I do this:

assertEquals(true, actual.matches(expectedRegex));

推荐答案

如果你使用 assertThat（ ）使用 Hamcrest匹配器测试正则表达式匹配，如果断言失败，你会收到一条表明预期模式和实际文本的好消息。断言也会更流利，例如。

If you use assertThat() with a Hamcrest matcher that tests for regex matches, then if the assertion fails you'll get a nice message that indicates expected pattern and actual text. The assertion will read more fluently also, e.g.

assertThat("FooBarBaz", matchesPattern("^Foo"));
