批注属性Test.enabled的值必须是常量表达式

Question

基本上，我想使用Context类的常量布尔属性，我通过反射更改了该属性，这样我就可以在testNG类中动态设置为testNG方法启用的@annotated。TestNG类有一个静态的final属性，该属性与Context.DISBLE_TEST_CASES_IF_OLD_ACK相同。我已经为TestNG类及其方法粘贴了下面的代码对我来说，最终目标是切换启用的值，或者基本上根据上下文禁用测试(如果是旧环境或新环境(

package com.abc.api.core.context;
import java.lang.reflect.Field;
import java.lang.reflect.Modifier;

public class Context {
public static final boolean DISBLE_TEST_CASES_IF_OLD_STACK = getConstantReflection();

public static boolean getConstantReflection()
{
System.out.println(DISBLE_TEST_CASES_IF_OLD_STACK);
try {
setEnableFlagBasedOnStackForTestCases();
} catch (NoSuchFieldException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println(Context.DISBLE_TEST_CASES_IF_OLD_STACK);
try {
final Field fld = Context.class.getDeclaredField("DISBLE_TEST_CASES_IF_OLD_STACK");
return (Boolean) fld.get( null );
} catch (NoSuchFieldException e) {
return (Boolean) null;
} catch (IllegalAccessException e) {
return (Boolean) null;
}
}
private static void setEnableFlagBasedOnStackForTestCases() throws NoSuchFieldException, SecurityException, IllegalArgumentException, IllegalAccessException{

Field f = Context.class.getDeclaredField("DISBLE_TEST_CASES_IF_OLD_STACK");
f.setAccessible(true);
//'modifiers' - it is a field of a class called 'Field'. Make it accessible and remove
//'final' modifier for our 'CONSTANT' field
Field modifiersField = Field.class.getDeclaredField( "modifiers" );
modifiersField.setAccessible( true );
modifiersField.setInt( f, f.getModifiers() & ~Modifier.FINAL );
if (TestcaseContext.getContext().equalsIgnoreCase(Context.OLD_STACK)) {
f.setBoolean(null, false);
}else {
f.setBoolean(null, true);
}
}
}

TESTNG类和方法示例：

package com.abc.api.test.tests.TestA;
import com.abc.api.core.context.Context;
public class TestA extends TestCommon {
private static final boolean ENABLE_DISABLE = Context.DISBLE_TEST_CASES_IF_OLD_STACK;
/**
* 
*/
@BeforeTest
void setPropertiesFile() {
......
}
/**
* PATCH Positive Test Cases
* 
*/
@Test(priority = 11, enabled=ENABLE_DISABLE)
public void testPositive1() {
......
}
}

为了有选择地禁用测试用例的最终目标，您可以使用TestNgs IAnnotationTransformer来控制启用的标志。它将在每个@Test注释的方法之前运行，并可以控制它的执行。

例如。

public class DemoTransformer implements IAnnotationTransformer {
public void transform(ITest annotation, Class testClass,
Constructor testConstructor, Method testMethod)
{
if (condition) {
annotation.setEnabled(false/true);
}
}
