用于在Jenkins控制台日志中查找特定文本的正则表达式

Question

我正在编写用于过滤Jenkins作业的Jenkins控制台日志的Python脚本，我想用正则表达式搜索特定的模式/文本。 以下是我要找的文字：

somename.SomeTest.testSomeName()

这是以下段落或句子的一部分：

Failed to find the annotation and the status of the test public void 
com.somename.qa.mobile.tests.somename.SomeTest.testSomeName().
The result is not deployed to Platform but we will proceed 
with further tests.......

上述句子在控制台日志中出现超过20次。我想找到每个实例 这个并获得该方法名称somename.SomeTest.testSomeName()。到目前为止，我已经尝试了\[([^\]]+)\] not deployed ([^ ]+)等等 作为此正则表达式的一部分缺失/不正确

以下是日志的小片段，我想从下面显示的每一个中找出test method name     Failed to find the annotation....句子：

21:18:19    at org.apache.maven.surefire.testng.TestNGExecutor.run(TestNGExecutor.java:170)
21:18:19    at org.apache.maven.surefire.testng.TestNGXmlTestSuite.execute(TestNGXmlTestSuite.java:84)

21:18:26    at somename.client.test.utilities.platform.PlatformApiClient.sendRequest(PlatformApiClient.java:197)
21:18:26    at

上面只是一个小片段;想象在日志中出现上述片段超过20次。

描述

^.*?(\[Error\]).*?\.((?:[a-z]+\.){2}[a-z]+\(\))

此正则表达式将执行以下操作：

• 找到[error]
的所有行
• 捕获方法名称，它是()
之前的三个文本块

Answer 2

我假设您可以扫描每行输出。试试这个正则表达式

.* ([^ ]+\(\)).*not deployed.*

示例如何使用Perl（regexp是相同的）

的示例

$ cat example | perl -ne 'print $1 if /([^ ]+\(\)).*not deployed/;'
com.somename.qa.mobile.tests.somename.SomeTest.testSomeName()
