according to the code, everything should be working...
- Add a unit test method called testNegativeMocking to ExternalSearchTests.cls that uses the HTTPMockFactory class to return a 500 response.
but : We can’t find the 'HttpMockFactory' being used to return a '500' response in the 'testNegativeMocking' method...
public class ExternalSearch {
public static HttpResponse search() {
HttpRequest req = new HttpRequest();
req.setEndpoint('https://api.example.com/search');
req.setMethod('GET');
try {
Http http = new Http();
return http.send(req);
} catch (Exception e) {
// System.debug('Exception occurred: ' + e.getMessage());
return null;
}
}
}
private class ExternalSearchTests {
// Test method for success scenario
@isTest
static void testPositiveMocking() {
Test.setMock(HttpCalloutMock.class, new HTTPMockFactory());
HttpResponse response = ExternalSearch.search();
System.assertEquals(200, response.getStatusCode());
}
// Test method for failure scenario
@isTest
static void testNegativeMocking() {
Test.startTest();
Test.setMock(HttpCalloutMock.class, new NegativeHTTPMockFactory());
HttpResponse response = ExternalSearch.search(); // This line is likely causing the NullPointerException
System.debug('Response: ' + response); // Add this debug statement to see if response is null
System.assertEquals(500, response.getStatusCode());
Test.stopTest();
}}
@IsTest
public class HTTPMockFactory implements HttpCalloutMock {
protected Integer code;
protected String status;
protected String body;
protected Map<String, String> responseHeaders;
public HTTPMockFactory(
Integer code,
String status,
String body,
Map<String, String> responseHeaders
) {
this.code = code;
this.status = status;
this.body = body;
this.responseHeaders = responseHeaders;
}
public HTTPResponse respond(HTTPRequest req) {
HttpResponse res = new HttpResponse();
for(String key : this.responseHeaders.keySet()) {
res.setHeader(key, this.responseHeaders.get(key));
}
res.setBody(this.body);
res.setStatusCode(this.code);
res.setStatus(this.status);
return res;
}
}
