我有一个junit测试试图使用MockUp()和@Mock Path get(String pathStr)来伪造Paths.get(String pathStr),它返回一个@Mocked Path路径; 在JMockit 1.23和1.22中,这工作正常,但是从JMockit 1.24开始到1.28,它抛出了一个mockit.internal.ClassFile $ NotFoundException,它引用的类也是TestClassName $ 2
new MockUp<Paths>() {
@Mock
public Path get(String first, String... more) {
return path;
}
};
对JMockit的每次更新似乎都会删除功能,但我真的不知道这里的主要罪行是什么。
更新:我现在知道MockUp是一个红色鲱鱼,问题是Expectations块不是作为匿名内部类创建的。我不明白为什么。
更新: 重现的代码:
package foo;
import mockit.Expectations;
import mockit.Mock;
import mockit.MockUp;
import mockit.Mocked;
import org.junit.Test;
import java.io.File;
import java.nio.file.Files;
import java.nio.file.LinkOption;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.time.Duration;
import static org.hamcrest.core.Is.is;
import static org.hamcrest.core.IsEqual.equalTo;
import static org.junit.Assert.assertThat;
public class ReproJMockitBug {
private Duration foo(File file, Path path, Duration duration) {
final boolean exists = Files.exists(path);
if (!exists && Paths.get("").equals(path)) {
System.out.print(file.getAbsolutePath());
return duration.plusMinutes(1);
}
return duration;
}
@Test
public void shouldReturnErrorForInvalidFilePath(@Mocked Duration duration, @Mocked File file, @Mocked Path path) {
String pathStr = "/some/test";
new MockUp<Paths>() {
@Mock
public Path get(String first, String... more) {
return path;
}
};
new MockUp<Files>() {
@Mock
public boolean exists(Path path, LinkOption... options) {
return false;
}
};
new Expectations() {{
onInstance(duration).plusMinutes(1);
result = Duration.ofMinutes(3);
onInstance(file).getAbsolutePath();
result = pathStr;
}};
assertThat(foo(file, path, duration), is(equalTo(Duration.ofMinutes(3))));
}
}
答案 0 :(得分:1)
这是一个更简单的复制器测试:
@Test
public void issue350Reproducer(@Mocked File file) {
new MockUp<Runnable>() {};
}
因此,使用Expectations
无关紧要。实际的错误在于模仿File
。
