当我在 Maven 中运行测试时,我得到以下信息:
[INFO] -------------------------------------------------------
[INFO] T E S T S
[INFO] -------------------------------------------------------
[INFO]
[INFO] Results:
[INFO]
[INFO] Tests run: 0, Failures: 0, Errors: 0, Skipped: 0
我的测试类 JsonReaderTest.class 位于src/测试/java据我从 maven-surefire-plugin 了解到,并遵循正确的名称约定。
在 Maven 外部运行时测试运行良好。
我的 pom 中包含这个插件:
<!-- Executes tests -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.20.1</version>
</plugin>
这在我的依赖项中:
<!-- Test -->
<dependency>
<groupId>org.junit.jupiter</groupId>
<artifactId>junit-jupiter-api</artifactId>
<version>5.0.0</version>
</dependency>
<dependency>
<groupId>org.junit.jupiter</groupId>
<artifactId>junit-jupiter-engine</artifactId>
<version>5.0.0</version>
</dependency>
和我的测试课:
package org.avalin.optaplanner.test.java;
import org.avalin.optaplanner.json.JsonReader;
import org.junit.jupiter.api.*;
import java.io.FileNotFoundException;
import java.nio.file.Paths;
import static org.junit.jupiter.api.Assertions.*;
public class JsonReaderTest
{
@Test
@DisplayName("Test: No such file at designated path")
void testloadFromJsonTest() throws Exception
{
Throwable exception = assertThrows(FileNotFoundException.class,
()-> JsonReader.loadFromJson(".json"));
assertEquals(".json (No such file or directory)",
exception.getMessage());
}
@Test
@DisplayName("Test: Load Shifts from JSON (String instead of number)")
void testLoadShiftsFromJson3()
{
Throwable exception = assertThrows(NumberFormatException.class, ()-> JsonReader.loadFromJson(Paths.get("src/main/resources/org/avalin/optaplanner/json/faultyShift-2.json").toAbsolutePath().toString()));
assertEquals("\nOne or more of your \"shift\" elements has a number format exception.\n" +
"Check for errors in your JSON-properties.\n" +
"(Did you insert a string instead of a number in id?)",
exception.getMessage());
}
@Test
@DisplayName("Test: JSON is correctly loaded")
void testJsonIsLoaded()
{
assertFalse(JsonReader.jsonIsLoaded());
}
@AfterEach
void cleanJsonReader()
{
JsonReader.cleanJsonReader();
}
}
当我尝试用谷歌搜索这个问题时,似乎唯一可能出错的是命名约定(类必须以 test 结尾或开始,我测试了两者,没有任何更改)并且测试类应该放入适当的文件夹中。
当我跑步时:mvn -Dtest=JsonReaderTest 测试
我得到以下信息:
Failed to execute goal org.apache.maven.plugins:maven-surefire-
plugin:2.20.1:test (default-test) on project optaplanner: No tests were
executed!
JsonReaderTest.class 也在目标/测试类中正确生成
这里的罪魁祸首可能是什么?
