输入依赖注入的安全枚举

I wanted an easy way for non coders to map new "Tests" with "Test" Types with the least amount of code change, using Guice for dependency injection. I like the simplicity, but not the obvious lack of type safety. Any suggestions to make this better?

我想要一个简单的方法让非编码人员使用Guice进行依赖注入,将新的“测试”与“测试”类型映射到最少的代码更改。我喜欢简单,但不是明显缺乏类型安全。有什么建议让这更好吗?

public enum TestType {

    TEST_TYPE_1("TEST-1", Test1.class), 
    TEST_TYPE_2("TEST-2", Test2.class), 
    TEST_TYPE_3("TEST-3", Test3.class), 
    TEST_TYPE_4("TEST-4", Test4.class), 
    TEST_TYPE_5("TEST-5", Test5.class);

    private final String testType;
    private final Class<TestIF> tester;

    private <TestIF> TestType(String testType, Class<TestIF> tester)    {       
        this.testType = testType;
        this.tester = (Class<tester.TestIF>) tester;
    }

    public String toString() {
        return this.testType;
    }

    public Class<TestIF> tester() {
        return this.tester;
    }
}

The "Test" would get instantiated like this:

“Test”会像这样实例化:

TestIF tester = Guice.createInjector().getInstance(testType.tester());    
tester.execute();

This helps force the Tests to implement TestIF, which is a bit safer in this case.

这有助于强制测试实现TestIF,在这种情况下更安全一些。

public enum TestType {

TEST_TYPE_1("TEST-1", Test1.class), 
TEST_TYPE_2("TEST-2", Test2.class), 
TEST_TYPE_3("TEST-3", Test3.class), 
TEST_TYPE_4("TEST-4", Test4.class), 
TEST_TYPE_5("TEST-5", Test5.class);

private final String testType;
private final Class<? extends TestIF> tester;

private <T extends TestIF> TestType(String testType, Class<? extends TestIF> tester)    {       
    this.testType = testType;
    this.tester = (Class<tester.TestIF>) tester;
}

public String toString() {
    return this.testType;
}

public Class<? extends TestIF> tester() {
    return this.tester;
}
