无法在@ParameterizedTest中使用@MethodSource

问题描述 投票：0回答：2

我正在尝试使用方法源创建参数化测试。以下是代码：

import java.util.stream.Stream;
import org.junit.jupiter.params.ParameterizedTest;
import org.junit.jupiter.params.provider.MethodSource;

class ABCTest {

    @ParameterizedTest
    @MethodSource("abc")
    void testABC(String word) {
        System.out.println(word);
    }

    static Stream<String> abc() {
        return Stream.of("a1",
                "b2");
    }

}

但这行不通；在尝试运行测试用例时，我

java.lang.NoSuchMethodError: 'java.lang.String[] org.junit.platform.commons.util.ReflectionUtils.parseQualifiedMethodName(java.lang.String)'
.
.
.
    Suppressed: org.junit.platform.commons.PreconditionViolationException: Configuration error: You must configure at least one set of arguments for this @ParameterizedTest
        at org.junit.platform.commons.util.Preconditions.condition(Preconditions.java:281)
        at org.junit.jupiter.params.ParameterizedTestExtension.lambda$provideTestTemplateInvocationContexts$5(ParameterizedTestExtension.java:98)

以下是我的

有人可以帮我吗？

尝试按照NoSuchMethodError: org.junit.platform.commons.util.ReflectionUtils.tryToLoadClass中的建议更改junit-jupiter-params的版本，仍然不起作用

正如 @johanneslink 所提到的，您的 lib 版本不匹配。您正在使用 

JUnit4
框架（特别是 
JUnit 4.12
），而 
@ParameterizedTest
注释（以及 
junit-jupiter-params
中的 
pom.xml
依赖项）属于 
Junit5
框架。

要将 

JUnit5
包含到您的项目中，请删除 
JUnit4
依赖项并将以下内容添加到您的 
pom.xml
中：

<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-engine</artifactId>
    <version>5.10.0</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-api</artifactId>
    <version>5.10.0</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-params</artifactId>
    <version>5.10.0</version>
    <scope>test</scope>
</dependency>

请注意，即使您使用 

JUnit5
，维护相同版本的依赖项也很重要。例如，将 
junit-jupiter-engine 5.10.0
与 
junit-jupiter-params 5.9.2
一起使用将导致代码无法工作。

另请注意，有一种方法可以使用 

JUnit4
创建参数化测试（参见此处），但无论如何我建议升级到 
JUnit5
，因为它总体上是一个更强大且更易于使用的框架。

对于 

@ParameterizedTest
与 
@MethodSource
的组合，您需要从您的方法返回一个参数流 
Stream<Arguments>
。 
Arguments
位于包装中 
package org.junit.jupiter.params.provider

例如：

private static Stream<Arguments> validPurchasePlatformGenerator() {
    return Arrays.stream(PurchasePlatform.values())
        .filter(purchasePlatform -> !purchasePlatform.equals(PurchasePlatform.WEB))
        .map(Arguments::of);
}

然后

@ParameterizedTest
@DisplayName("Some DisplayText")
@MethodSource("validPurchasePlatformGenerator")
void purchaseValid_shouldReturnValidResult(PurchasePlatform purchasePlatform) { 
    // test code
}

如果您只想使用纯字符串，您也可以使用 

@ValueSource
而不是 
@MethodSource
，这对您提供的测试更有意义。

例如

@ParameterizedTest
@ValueSource(strings = { "a1", "a2" })
void testABC(String word) {
    System.out.println(word);
}
