通过不使用Maven的可执行JAR从cmdline执行Cucumber测试

Question

步骤1：在此基础上，我使用maven-shade-plugin构建了一个包含所有依赖项的独立jar。

pom.xml

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.22.2</version>
            <configuration>
                <testFailureIgnore>true</testFailureIgnore>
                <testSourceDirectory>${basedir}/src/main/java/</testSourceDirectory>
                <testClassesDirectory>${project.build.directory}/classes/</testClassesDirectory>
                <reportsDirectory>${project.build.directory}/test-output/${timestamp}</reportsDirectory>
            </configuration>
        </plugin>
        <!-- https://maven.apache.org/plugins/maven-shade-plugin/examples/executable-jar.html -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <version>3.2.1</version>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                    <configuration>
                        <!-- https://maven.apache.org/plugins/maven-shade-plugin/shade-mojo.html -->
                        <shadedArtifactAttached>true</shadedArtifactAttached>
                        <shadedClassifierName>standalone</shadedClassifierName>
                        <transformers>
                            <!-- https://maven.apache.org/plugins/maven-shade-plugin/examples/resource-transformers.html -->
                            <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                                <mainClass>runners.RunCukesTest</mainClass>
                            </transformer>
                        </transformers>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

将main()方法添加到runner类，并根据this、this和this传递cmdline arg。

package runners;

import cucumber.api.CucumberOptions;
import cucumber.api.SnippetType;
import cucumber.api.cli.Main;
import cucumber.api.testng.AbstractTestNGCucumberTests;

@CucumberOptions(features = { "src/main/resources/features" }, glue = { "steps" }, tags = { "not @ignore" }, plugin = {
        "pretty" }, monochrome = true)
public class RunCukesTest extends AbstractTestNGCucumberTests {

    public static void main(String[] args) {
        System.out.println("Begin running tests...");
        Main.main(new String[]{ "-g", "steps", "-t", "not @ignore", "-p", "pretty", "-m", "src/main/resources/features" });
    }

}

λ java -jar project-xyz-1.0.0-standalone.jar
Begin running tests...

Main.main(new String[]{ "-g", "steps", "-t", "not @ignore", "-p", "pretty", "-m", "src/main/resources/features" });

如何通过cmdline args指向JAR中的features目录？

Answer 1

您将一个相对路径传递给Cucumbersrc\main\resources\features。因为您正在执行Jar，所以使用当前工作目录将这个相对路径转换为绝对路径。但是，因为src\main\resources\features是您的特性的源文件夹，所以找不到任何特性，您会得到：

线程“main”java.lang.IllegalArgumentException:不是文件或目录:\path\to\jar\src\main\resources\features

相反，您必须告诉Cucumber，您的特性在类路径上。您可以通过以下方式完成：

"classpath:features"
