如何在Fitnesse测试中加载自定义比较器

Question

I created a custom comparator for Fitnesse, and attempted to load it, but I can't get it to work. It's just completely ignored in my script table, and it does a direct string equality comparison.

Comparator:

package com.company;
import fitnesse.testsystems.slim.CustomComparator;

public class ContainsComparator implements CustomComparator{

    @Override
    public boolean matches(String actual, String expected) {
        if(actual != null && actual.contains(expected)){
            return true;
        }
        else{
            return false;   
        }
    }
}

Test Page contents:

!define TEST_SYSTEM {slim}
!path C:\Path\To\My\Comparator.jar

!|Import|
|fitnesse.fixtures|

!| SetUp | CustomComparators=contains:com.company.ContainsComparator |

!|Script|com.company.SomeFixture|
|check| response|contains:something|

Only the last check fails, returning: [Something there] expected [contains:Something]. There's no other exceptions or failures (Setup doesn't throw an error, for example)

I followed examples from http://fitnesse.org/FitNesse.SuiteAcceptanceTests.SuiteSlimTests.TestCustomComparators and http://www.fitnesse.org/FitNesse.UserGuide.AdministeringFitNesse.ConfigurationFile to get this far, but I can't find any further documentation on this.

Answer 1

尝试通过plugins.properties文件注册自定义比较器。

Answer 2

For those who (like me) were still not able to get this working after applying the accepted answer and the comments on the question: if you run fitnesse using fitnesse-standalone.jar , plugins are only looked for within jar files in the plugins directory. Placing class files there won't work.

Also, a URLClassLoader is used to look inside the jar files, so make sure the class file is inside directories corresponding to its package. For example, the jar file containing ContainsComparator from the question should have the following directory structure:

.
+-- com
    +-- company
        +-- ContainsComparator.class
