通过Maven surefire-report在汇总格式的单个文件中的单元测试类中的测试执行时间 [英] Execution time of tests in unit test class via maven surefire-report in a single file in summarized format

问题描述

谁能让我知道如何通过maven-surefire在单个文件中获得单元测试类中每个单元测试所花费的时间?我已经看到target/surefire-report包含每个测试的文件.基本上，我正在寻找一个汇总了所有执行时间的文件.如果可能的话，还可以按每个测试的执行时间对结果进行排序.

Can anyone let me know how can I get the time taken by each of the unit tests in a unit test class in a single file via maven-surefire? I have seen my target/surefire-report it has files for each test. Basically I am looking for a single file with all the execution times summarized. If possible also sort the result by execution time of each test.

我正在使用Maven 3.5& MacOSX 10.12.6上的surefire-plugin 2.4.2.

推荐答案

maven-surefire-plugin当前不允许您执行此操作.它将所有结果写入单独的文件中.如果您感觉是这样，则可以在其问题跟踪器中创建功能请求.缺少的功能.

The maven-surefire-plugin currently doesn't let you do this. It writes all the results in separate files. You could create a feature-request in its issue tracker, if you feel like this is a missing feature.

但是，您可以使用一些Linux命令将输出转换为所需的输出.以下是一些命令，可将单独的XML文件转换为看起来像您想要的文件:

However you can use some Linux commands to convert the output to what you need. Here are some commands that turn the separate XML files into a single file that looks like what you want:

grep testcase target/surefire-reports/TEST-*.xml |
  sed 's/.* name="\(.*\)" classname="\(.*\)" time="\(.*\)".*/\2#\1() - \3ms/g' |
  sort -n -k 3 > output.txt

更新:数值排序存在分数变化的问题 数字.使用下面的awk版本来解决此问题.

Update: Numeric sorting has problems with varying number of fraction digits. Use awk version below to solve this.

使用awk可以做的更短，而且不那么隐秘:

The same thing could be done with awk a bit shorter and less cryptic:

grep -h testcase target/surefire-reports/TEST-*.xml |
  awk -F '"' '{printf("%s#%s() - %.3fms\n", $4, $2, $6); }' |
  sort -n -k 3 > output.txt

在生成surefire报告后，您必须从maven项目的顶级目录中执行这些命令.

You have to execute these commands from the toplevel directory of your maven project after the surefire-reports were generated.

如果您有多模块项目，请改用此项目:

If you have multi-module project, use this instead:

find . -name TEST-*.xml -exec grep -h testcase {} \; |
  awk -F '"' '{printf("%s#%s() - %.3fms\n", $4, $2, $6); }' |
  sort -n -k 3 > output.txt

结果文件为output.txt，并包含以下格式的行:

The resulting file is output.txt and contains lines of the following format:

<classname>#<methodname>() - <time>ms

结果按消耗的时间排序.

The result is sorted by consumed time.
