我已经使用Java,Selenium,Junit,Maven开发了一整套的自动化测试。
对于每个测试,它们都有一个或多个@Category注释,用于描述每个测试涵盖的软件区域。例如:
@Test
@Category({com.example.core.categories.Priority1.class,
com.example.core.categories.Export.class,
com.example.core.categories.MemberData.class})
@Test
@Category({com.example.core.categories.Priority1.class,
com.example.core.categories.Import.class,
com.example.core.categories.MemberData.class})
@Test
@Ignore
@Category({com.example.core.categories.Priority2.class,
com.example.core.categories.Import.class,
com.example.core.categories.MemberData.class})
我想做的是找到一种方法来计算包含给定类别的测试数量。所有可能的类别都是//com/example/core/categories
文件夹中的文件名作为源列表。
我已经尝试构建一个shell脚本来进行字数统计,这似乎还可以,但是我认为会有更多的“内置”来处理@Category。
我最大的问题是,即使我得到了正确的计数,也很有可能将一个或多个测试标记为@Ignore,这应该使该测试@Category无效,但无需大量使用标志并读取每个文件行-按顺序排列,以排除正确的计数。
是否有一种很好的方法可以逐项列出@Category的内容,而这也是@Ignore的因素呢?
示例输出
| Category | Count |
|----------------------------------------------|------:|
| com.example.core.categories.Export.class | 1 |
| com.example.core.categories.Import.class | 1 |
| com.example.core.categories.MemberData.class | 2 |
| com.example.core.categories.Priority1.class | 2 |
| com.example.core.categories.Priority2.class | 0 |
| com.example.core.categories.Priority3.class | 0 |

我尝试了一种使用抽象层中的计数器执行此操作的方法,但是这很痛苦,必须在每个Test方法的开头添加源代码。
最后,这是我为满足您的需求而编写的源代码。它相当沉重(反射...),但是它对现有源代码的干扰较小,可以完全满足您的需求。
首先,您必须创建一个Testsuite
(包含各种其他套件,或者直接包含您想要的所有Test类),以确保最后已加载了您想要统计的所有Test。
在此套件中,您必须实现一个名为“ @AfterClass
”的“最终挂钩”,当整个测试套件已由 JUnit 完全管理时,它将被一次调用。
这是我为您编写的测试套件实现:
package misc.category;
import java.lang.annotation.Annotation;
import java.lang.reflect.Method;
import java.util.HashMap;
import java.util.Map;
import java.util.Map.Entry;
import java.util.Vector;
import java.util.concurrent.atomic.AtomicInteger;
import org.junit.AfterClass;
import org.junit.runner.RunWith;
import org.junit.runners.Suite;
@RunWith(Suite.class)
@Suite.SuiteClasses({ UnitTestWithCategory.class })
public class TestSuiteCountComputer {
public static final String MAIN_TEST_PACKAGES = "misc.category";
private static final Class<?>[] getClasses(final ClassLoader classLoader)
throws NoSuchFieldException, SecurityException, IllegalArgumentException, IllegalAccessException {
Class<?> CL_class = classLoader.getClass();
while (CL_class != java.lang.ClassLoader.class) {
CL_class = CL_class.getSuperclass();
}
java.lang.reflect.Field ClassLoader_classes_field = CL_class.getDeclaredField("classes");
ClassLoader_classes_field.setAccessible(true);
Vector<?> classVector = (Vector<?>) ClassLoader_classes_field.get(classLoader);
Class<?>[] classes = new Class[classVector.size()]; // Creates an array to avoid concurrent modification
// exception.
return classVector.toArray(classes);
}
// Registers the information.
private static final void registerTest(Map<String, AtomicInteger> testByCategoryMap, String category) {
AtomicInteger count;
if (testByCategoryMap.containsKey(category)) {
count = testByCategoryMap.get(category);
} else {
count = new AtomicInteger(0);
testByCategoryMap.put(category, count);
}
count.incrementAndGet();
}
@AfterClass
public static void tearDownAfterClass() throws Exception {
Map<String, AtomicInteger> testByCategoryMap = new HashMap<>();
ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
while (classLoader != null) {
for (Class<?> classToCheck : getClasses(classLoader)) {
String packageName = classToCheck.getPackage() != null ? classToCheck.getPackage().getName() : "";
if (!packageName.startsWith(MAIN_TEST_PACKAGES))
continue;
// For each methods of the class.
for (Method method : classToCheck.getDeclaredMethods()) {
Class<?>[] categoryClassToRegister = null;
boolean ignored = false;
for (Annotation annotation : method.getAnnotations()) {
if (annotation instanceof org.junit.experimental.categories.Category) {
categoryClassToRegister = ((org.junit.experimental.categories.Category) annotation).value();
} else if (annotation instanceof org.junit.Ignore) {
ignored = true;
} else {
// Ignore this annotation.
continue;
}
}
if (ignored) {
// If you want to compute count of ignored test.
registerTest(testByCategoryMap, "(Ignored Tests)");
} else if (categoryClassToRegister != null) {
for (Class<?> categoryClass : categoryClassToRegister) {
registerTest(testByCategoryMap, categoryClass.getCanonicalName());
}
}
}
}
classLoader = classLoader.getParent();
}
System.out.println("\nFinal Statistics:");
System.out.println("Count of Tests\t\tCategory");
for (Entry<String, AtomicInteger> info : testByCategoryMap.entrySet()) {
System.out.println("\t" + info.getValue() + "\t\t" + info.getKey());
}
}
}
您可以适应您的需求,尤其是我一开始创建的常量,以过滤要考虑的软件包。
然后,您无所事事。
例如,这是我很小的测试类:
package misc.category;
import org.junit.Test;
import org.junit.experimental.categories.Category;
public class UnitTestWithCategory {
@Category({CategoryA.class, CategoryB.class})
@Test
public final void Test() {
System.out.println("In Test 1");
}
@Category(CategoryA.class)
@Test
public final void Test2() {
System.out.println("In Test 2");
}
}
在这种情况下,输出为:
In Test 1
In Test 2
Final Statistics:
Count of Tests Category
1 misc.category.CategoryB
2 misc.category.CategoryA
并带有包含@Ignore
批注的测试用例:
package misc.category;
import org.junit.Ignore;
import org.junit.Test;
import org.junit.experimental.categories.Category;
public class UnitTestWithCategory {
@Category({CategoryA.class, CategoryB.class})
@Test
public final void Test() {
System.out.println("In Test 1");
}
@Category(CategoryA.class)
@Test
public final void Test2() {
System.out.println("In Test 2");
}
@Category(CategoryA.class)
@Ignore
@Test
public final void Test3() {
System.out.println("In Test 3");
}
}
您将获得输出:
In Test 1
In Test 2
Final Statistics:
Count of Tests Category
1 (Ignored Tests)
1 misc.category.CategoryB
2 misc.category.CategoryA
您可以根据需要轻松删除“(已忽略的测试)”注册,并且当然可以根据需要调整输出。
这个最终版本非常棒的一点是,它将处理已经真正加载/执行的测试类,因此您将获得关于已执行内容的真实统计信息,而不是像您这样的静态统计信息到目前为止。
如果您希望像您所要求的那样与现有源代码无关,那么这是一种静态执行按类别进行测试计算的方法。

您只需要在开始时修改两个常量即可指定:

来考虑100%可用的软件包)这个新版本的想法:
如果您需要更多信息,请告诉我。
答案 1 :(得分:0)
使用番石榴ClassPath
,您可以执行以下操作:
首先加载类别:
private static List<Class<?>> getCategories(ClassPath classPath) {
return classPath.getAllClasses()
.stream()
.filter(classInfo -> classInfo.getPackageName().startsWith(CATEGORIES_PACKAGE))
.map(ClassPath.ClassInfo::load)
.collect(Collectors.toList());
}
然后计数频率。
此方法从类别Map
返回一个Class<?>
到它的频率:
private static Map<Class<?>, Long> getCategoryFrequency(ClassPath classPath) {
return classPath.getAllClasses()
.stream()
.filter(classInfo -> classInfo.getPackageName().startsWith(APPLICATION_PACKAGE))
.map(ClassPath.ClassInfo::load)
.map(Class::getMethods)
.flatMap(Arrays::stream)
.filter(method -> method.getAnnotation(Test.class) != null)// Only tests
.filter(method -> method.getAnnotation(Ignore.class) == null) // Without @Ignore
.map(method -> method.getAnnotation(Category.class))
.filter(Objects::nonNull)
.map(Category::value)
.flatMap(Arrays::stream)
.collect(groupingBy(Function.identity(), Collectors.counting()));
}
最后打印结果:
System.out.println("Category | Frequency");
for (Class<?> category : categories) {
System.out.println(category.getSimpleName() + " | " + categoryFrequency.getOrDefault(category, 0L));
}
完整的课程清单:
public class CategoriesCounter {
private static final String CATEGORIES_PACKAGE = "com.example.core.categories";
private static final String APPLICATION_PACKAGE = "com.example.core";
public static void main(String[] args) throws Throwable {
ClassPath classPath = ClassPath.from(CategoriesCounter.class.getClassLoader());
List<Class<?>> categories = getCategories(classPath);
Map<Class<?>, Long> categoryFrequency = getCategoryFrequency(classPath);
System.out.println("Category | Frequency");
for (Class<?> category : categories) {
System.out.println(category.getSimpleName() + " | " + categoryFrequency.getOrDefault(category, 0L));
}
}
private static List<Class<?>> getCategories(ClassPath classPath) {
return classPath.getAllClasses()
.stream()
.filter(classInfo -> classInfo.getPackageName().startsWith(CATEGORIES_PACKAGE))
.map(ClassPath.ClassInfo::load)
.collect(Collectors.toList());
}
private static Map<Class<?>, Long> getCategoryFrequency(ClassPath classPath) {
return classPath.getAllClasses()
.stream()
.filter(classInfo -> classInfo.getPackageName().startsWith(APPLICATION_PACKAGE))
.map(ClassPath.ClassInfo::load)
.map(Class::getMethods)
.flatMap(Arrays::stream)
.filter(method -> method.getAnnotation(Test.class) != null)// Only tests
.filter(method -> method.getAnnotation(Ignore.class) == null) // Without @Ignore
.map(method -> method.getAnnotation(Category.class))
.filter(Objects::nonNull)
.map(Category::value)
.flatMap(Arrays::stream)
.collect(groupingBy(Function.identity(), Collectors.counting()));
}
}
将这个测试类放在类路径中:
public class Test1 {
@FastTest
@Category(value = FastTest.class)
@Test
public void a() {
}
@FastTest
@Category(value = FastTest.class)
@Test
public void d() {
}
@Category(value = SlowTest.class)
@Test
public void b() {
}
@Category(value = SlowTest.class)
@Test
@Ignore
public void c() {
}
}
CategoriesCounter
产生:
Category | Frequency
SlowTest | 1
FastTest | 2
