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控制台日志以进行Jenkins作业的Python脚本，并且我想用正则表达式搜索特定模式/文本。 下面是我要寻找的文字：

somename.SomeTest.testSomeName() 

这是继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....... 

这样的句子以上存在于控制台日志超过20倍。我想查找 这个的每个实例并获得该方法名称somename.SomeTest.testSomeName()。我曾尝试这个迄今\[([^\]]+)\] not deployed ([^ ]+)和东西 缺少/不正确的，这个正则表达式

以下的部分是日志的小片段，我想找出每个以下test method name所示 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) 
21:18:19 at org.apache.maven.surefire.testng.TestNGProvider.invoke(TestNGProvider.java:92) 
21:18:19 at org.apache.maven.surefire.booter.ForkedBooter.invokeProviderInSameClassLoader(ForkedBooter.java:200) 
21:18:19 at org.apache.maven.surefire.booter.ForkedBooter.runSuitesInProcess(ForkedBooter.java:153) 
21:18:19 at org.apache.maven.surefire.booter.ForkedBooter.main(ForkedBooter.java:103) 
21:18:26 2016-05-12 21:18:25.238 [ERROR] (1): 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 
21:18:26 somename.client.test.utilities.Platform.PlatformApiException: Platform API returned HTTP 400("Field :case_id is not a valid test case.") 
21:18:26 at somename.client.test.utilities.platform.PlatformApiClient.sendRequest(PlatformApiClient.java:197) 
21:18:26 at 

以上只是一小段代码片段;设想在日志中出现以上片段超过20次。

Answer 1

我假设你可以扫描每行的输出。试试这个正则表达式

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

实例它的运作方式使用Perl的例子（正则表达式是相同的）

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

Answer 2

说明

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

此正则表达式会做以下：

• 找到所有与[error]
• 捕获方法名称，其是文本的三个斑点的()
