参数从XML传递的Junit4测试实现,(属性值+节点值)?

Junit4 test implementation with parameters passed from XML, (attribute value + nodevalue)?

我知道我可以对其进行硬编码(解析 xml,提取),但是有没有一种方法可以像使用 Feed4TestNG 那样提供(属性值 + 节点值)(它目前仅支持 csv,并且 excel 个文件)?

我是 Java 的新手,任何专家见解都会有所帮助。谢谢!

@Parameters 的主体不仅限于数据,您可以在此方法中使用您喜欢的任何 java 代码,包括抛出异常:

@Parameters
public static Collection<Object[]> data() throws IOException {
    List<Object[]> data = new ArrayList<>();
    // replace getClass() with <nameofclass>.class
    try(InputStream in = this.getClass().getResourceAsStream()) { 
        //parse body here
        data.add(new Object[]{attribute, value});
    }
    return data;
}

根据您使用的 XML 框架,您需要解析 XML 节点,并将其放入列表中,您将要 return.

这就是我最终在这里做的事情:

如果您认为我可以改进我的代码,请提交您的更正。 .

@RunWith(Parameterized.class) public class DataDrivenTests {

private String c;
private String b;
private static Collection<Object[]> a;
@Parameters
public static Collection<Object[]> xmlData() throws IOException{

        File file = new File("xmlfile.xml");
        InputStream xml1 = new FileInputStream(file);
        return  new xmlData(xml1).getData();

}



public DataDrivenTests(String c, String b) {
    super();
    this.c = c;
    this.b = b;


}


@Test
public void shouldCalculateATimesB() {
    boolean assertion = false;

    if(c.equals(Parser.parse("Parse this string to Attribute and Value"))){
        assertion = true;

    }

    assertTrue(assertion);


}

}
