TestNG：通过TestNG运行测试时“未找到测试”

Question

我试图通过testng运行简单的Cucumber/Java测试。xml。

所以，我有testng。xml:

<?xml version="1.0" encoding="UTF-8"?>
        <!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Cucumber Framework">
<test name="Cucumber Tests" junit="true">
    <classes>
        <class name="CucumberFramework.runner.MainRunner"></class>
    </classes>
</test>
</suite>

我用的是runner。类，在其中我将路径/选项/etc设置为功能文件、步骤和报告：

package CucumberFramework.runner;

import cucumber.api.CucumberOptions;
import cucumber.api.junit.Cucumber;
import cucumber.api.testng.AbstractTestNGCucumberTests;
import org.junit.runner.RunWith;

@RunWith(Cucumber.class)

@CucumberOptions (
        features = {"src/test/java/CucumberFramework/featureFiles"},
        glue = {"CucumberFramework.steps"},
        monochrome = true,
        tags = {},
        plugin = {"pretty",
                "html:target/cucumber",
                "json:target/cucumber.json",
                "com.cucumber.listener.ExtentCucumberFormatter:target/report.html"}
)

public class MainRunner extends AbstractTestNGCucumberTests {
}

但是当我运行testng时。xml作为TestNG套件，它：

1） 通过我自己的设想，

但是

我做错了什么？

Answer 1

需要添加@Test注释才能运行。

Answer 2

带有Cucumber和TestNG的项目不需要具有用@Test注释的方法的类。

未找到测试可能与您运行测试的方式有关。

在下面找到一个显示基本需求的最小项目。

假设以下结构

src/test/java/stepdef/StepDefs.java
src/test/java/runner/RunnerTest.java
src/test/resources/features/test.feature
pom.xml

波姆。xml

    </properties>
</project>

test.feature

Feature: test
    Scenario: something to test
        Given some step
        Then this is expected

StepDefs.java

package stepdef;

import cucumber.api.java.en.Given;
import cucumber.api.java.en.Then;

public class StepDefs {
    @Given("^some step$")
    public void someStep() throws Throwable {
        System.out.println("execute someStep");
    }

    @Then("^this is expected$")
    public void thisIsExpected() throws Throwable {
        System.out.println("execute thisIsExpected");
    }
}

RunnerTest。JAVA

package runner;

import cucumber.api.CucumberOptions;
import cucumber.api.testng.AbstractTestNGCucumberTests;

@CucumberOptions(features = "src/test/resources/features", glue = "stepdef")
public class RunnerTest extends AbstractTestNGCucumberTests {
}

测试可以通过Maven执行

mvn clean test

输出

-------------------------------------------------------
 T E S T S
-------------------------------------------------------
Running runner.RunnerTest
Configuring TestNG with: org.apache.maven.surefire.testng.conf.TestNG652Configurator@5eb5c224

1 Scenarios (1 passed)
2 Steps (2 passed)
0m0.019s

Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.552 sec

正如最后一行所述，测试运行：1cucumber场景被识别为测试运行。

编辑将Cumber测试作为TestNG套件执行的可能性。

添加到pom.xml

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.22.0</version>
            <configuration>
                <suiteXmlFiles>
                    <suiteXmlFile>testng.xml</suiteXmlFile>
                </suiteXmlFiles>
            </configuration>
        </plugin>
    </plugins>
</build>

创建文件testng。xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Cucumber Framework" >
    <test name="Cucumber Tests">
        <classes>
            <class name="runner.RunnerTest"></class>
        </classes>
    </test>
</suite>

使用Maven作为执行测试

mvn clean test

输出

[INFO] -------------------------------------------------------
[INFO]  T E S T S

Answer 3

@SubOptimal-谢谢你如此清晰的解释，现在我知道得更多了。

关于问题本身——最后我通过删除testng中提到的junit解决了它。xml。正如我在描述中提到的“作为testng套件运行”，我应该将这个答案标记为正确，没有冒犯。
