maven - 如何衡量 RestFul API 的代码覆盖率

Question

我有一个基于 Maven 的多模块 Jersey 项目，它公开了很少的 RestFul API。项目结构就像 -

项目

• 模块 1

  ------------源

  --------单元测试

• 模块 2

  ------------源

  --------单元测试

• 模块 3

  ------------源

  --------单元测试

• ModuleN - 此模块包含集成测试，它将命中项目公开的端点并像黑盒一样测试整个服务

  ------------源

  --------单元测试

我想构建这个项目并在构建阶段执行单元测试，然后创建一个 jar，将这个 jar 部署到某个地方，执行集成测试(它存在于项目的一个模块中，这将达到 REST 端点)然后我想要测量组合覆盖率(单元+集成测试)。

我浏览了很多博客和文章，但到处都是半信息。有人可以指点我或指导我该怎么做。

谢谢-沙希德

Answer 1

正如我回答的here:您可以将所有报告放在一个文件夹中(不要忘记调用不同的文件夹!)并为此使用合并 mojo，或者通过添加标志“附加”为所有报告使用一个中央唯一文件:

-javaagent:append=true,destFile=/home/YourProject/report.exec

[此处][2] 您将找到有关如何配置代理的更多信息。

希望对您有所帮助!

编辑:

只要您要求不同类型的执行(单元和集成)，我假设您使用不同的插件来执行测试。

您需要做的是准备两个 JaCoCo 代理并将它们的 argLine 提供给将运行您的测试的插件:

        <plugin>
            <groupId>org.jacoco</groupId>
            <artifactId>jacoco-maven-plugin</artifactId>
            <version>0.7.7.201606060606</version>
            <executions>
                <!--
                    Prepares the property pointing to the JaCoCo runtime agent which
                    is passed as VM argument when Maven the Surefire plugin is executed.
                -->
                <execution>
                    <id>pre-unit-test</id>
                    <goals>
                        <goal>prepare-agent</goal>
                    </goals>
                    <configuration>
                        <!-- Sets the path to the file which contains the execution data. -->
                        <destFile>${project.build.directory}/jacoco.exec</destFile>
                        <!--
                            Sets the name of the property containing the settings
                            for JaCoCo runtime agent.
                        -->
                        <propertyName>surefireArgLine</propertyName>
                    </configuration>
                </execution>
                <!--

                    unit tests have been run.

                <execution>
                    <id>post-unit-test</id>
                    <phase>test</phase>
                    <goals>
                        <goal>report</goal>
                    </goals>
                    <configuration>
                        <!-- Sets the path to the file which contains the execution data. -->
                        <dataFile>${project.build.directory}/jacoco.exec</dataFile>
                        <!-- Sets the output directory for the code coverage report. -->
                        <outputDirectory>${project.reporting.outputDirectory}</outputDirectory>
                    </configuration>
                </execution>
                        <!-- The Executions required by unit tests are omitted. -->
                <!--
                    Prepares the property pointing to the JaCoCo runtime agent which
                    is passed as VM argument when Maven the Failsafe plugin is executed.
                -->
                <execution>
                    <id>pre-integration-test</id>
                    <phase>pre-integration-test</phase>

                        <!--
                            Sets the name of the property containing the settings
                            for JaCoCo runtime agent.
                        -->
                        <propertyName>failsafeArgLine</propertyName>
                    </configuration>
                </execution>
                 <!--
                    Ensures that the code coverage report for integration tests after
                    integration tests have been run.
                -->
                <execution>
                    <id>post-integration-test</id>
                    <phase>post-integration-test</phase>
                    <goals>
                        <goal>report</goal>
                    </goals>
                    <configuration>
                        <!-- Sets the path to the file which contains the execution data. -->
                        <dataFile>${project.build.directory}/jacoco-it.exec</dataFile>
                        <!-- Sets the output directory for the code coverage report. -->
                        <outputDirectory>${project.reporting.outputDirectory}</outputDirectory>
                    </configuration>
                </execution>
            </executions>
        </plugin>

然后您必须配置您的插件(通常使用 failsafe 和 surefire)以接受为 JaCoCo 代理创建的 argLine:

            <plugin>
                <artifactId>maven-surefire-plugin</artifactId>
                <configuration>
                    <argLine>${surefireArgLine}</argLine>
                </configuration>
            </plugin>

故障安全插件也是如此。
