用于捕获 Maven 测试输出的正则表达式

发布于 2025-01-10 12:26:31 字数 921 浏览 0 评论 0原文

当我运行测试时，我有这个 Maven 输出：

...
[INFO] 
[ERROR] Tests run: 77, Failures: 0, Errors: 2, Skipped: 0
[INFO] 
[INFO] ------------------------------------------------------------------------
[INFO] BUILD FAILURE
[INFO] ------------------------------------------------------------------------
[INFO] Total time:  42:09 min
[INFO] Finished at: 2022-02-25T10:40:21Z
[INFO] ------------------------------------------------------------------------
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:3.0.0-M5:test (default-test) on project ***-***-******-*****: There are test failures.
[ERROR]
...

我想用 Regex 或其他方式捕获这一行：

Tests run: 77, Failures: 0, Errors: 2, Skipped: 0

我不需要准确地捕获它，但至少需要捕获一般区域，因为每个测试类都会生成自己的测试摘要由于

到目前为止，我想出的正则表达式是：

((?<=\[ERROR\]).*\n).*((?=BUILD).*\n)

某种原因，它不起作用。

我该怎么做？

原文

I have this Maven output when I run my tests:

...
[INFO] 
[ERROR] Tests run: 77, Failures: 0, Errors: 2, Skipped: 0
[INFO] 
[INFO] ------------------------------------------------------------------------
[INFO] BUILD FAILURE
[INFO] ------------------------------------------------------------------------
[INFO] Total time:  42:09 min
[INFO] Finished at: 2022-02-25T10:40:21Z
[INFO] ------------------------------------------------------------------------
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:3.0.0-M5:test (default-test) on project ***-***-******-*****: There are test failures.
[ERROR]
...

I want to capture this line with Regex or otherwise:

Tests run: 77, Failures: 0, Errors: 2, Skipped: 0

I don't need to capture it exactly, but at least the general area, as each test class produces its own test summary of tests run, passed etc.

The RegEx I have come up with so far is:

((?<=\[ERROR\]).*\n).*((?=BUILD).*\n)

Which doesn't work for some reason.

How can I do this?

您可以

\[ERROR](.*)(?:\n(?!.* BUILD\b|\[ERROR]).*)*\n.* BUILD\b

在部分中使用模式匹配：

\[ERROR\] 匹配 [ERROR]
(.*) 捕获组 1，匹配整行
(?: 非捕获组
- \n 匹配换行符
- (?! 断言右侧的内容不是负向前瞻
  - .* BUILD\b 匹配行中的 BUILD
  - | 或者
  - \[ERROR] 匹配 [ERROR]
- ) 关闭前瞻
- .* 匹配整行
)* 关闭非捕获组并可选择重复
\n .* BUILD\b 匹配换行符并的行

BUILD Regex demo

You could use

\[ERROR](.*)(?:\n(?!.* BUILD\b|\[ERROR]).*)*\n.* BUILD\b

In parts, the pattern matches:

\[ERROR\] Match [ERROR]
(.*) Capture group 1, match the whole line
(?: Non capture group
- \n Match a newline
- (?! A negative lookahead to assert what is to the right is not
  - .* BUILD\b Match BUILD in the line
  - | Or
  - \[ERROR] Match [ERROR]
- ) Close the lookahead
- .* Match the whole line
)* Close non capture group and optionally repeat
\n.* BUILD\b Match a newline and the line with BUILD
