Junit在assertTrue字符串比較中返回錯誤

Question

 StringWriter result = runMethod.getOutput(); 
    String expected = "<3>textValue</3>" 
    assertTrue("Should have contained the required result", result.toString().contains(expected)); 

爲什麼Junit在此處返回錯誤？

Answer 1

我剛試過這個，它工作正常。

如果字符串不匹配，它會給出以下錯誤。 java.lang.AssertionError：應載有所需的結果

import static org.junit.Assert.assertTrue; 

import java.io.StringWriter; 

import org.junit.Test; 

public class XYZ 
{ 

    @Test 
    public void test() 
    { 

     StringWriter result = new StringWriter(); 
     result.append("<3>textValue</3>"); 
     String expected = "<3>textValue</3>"; 
     assertTrue("Should have contained the required result", result.toString().contains(expected)); 
    } 

}
