Apex test classes for the BitlyService. The .java extension is just for syntax highlighting, save them as .cls in your project.
@IsTest
public class BitlyHttpCalloutMock implements HttpCalloutMock {
public HttpResponse respond(HttpRequest req) {
String endpoint = req.getEndpoint();
if ( endpoint.contains('/oauth/access_token') ) {
return buildOAuthResponse( req );
} else if ( endpoint.contains('/v4/shorten') ) {
return buildShortenResponse( req );
}
return null;
}
private HttpResponse buildOAuthResponse(HttpRequest req) {
HttpResponse res = new HttpResponse();
res.setBody('123');
res.setStatusCode(200);
return res;
}
private HttpResponse buildShortenResponse(HttpRequest req) {
HttpResponse res = new HttpResponse();
// See https://dev.bitly.com/api-reference#createBitlink
// for full details of what a response could include.
res.setBody(JSON.serializePretty(new Map<String, Object>{
'link' => 'https://sforce.co/3rUWGZ8'
}));

@IsTest
static void test_shorten() {
Test.startTest();
Test.setMock(HttpCalloutMock.class, new BitlyHttpCalloutMock());
BitlyService service = new BitlyService();

String shortURL = service.shorten(longURL);

System.assertEquals('https://sforce.co/3rUWGZ8', shortURL);
}
}
@IsTest
private class BitlyShortenURLInvocableTest {
@IsTest
static void test_shorten() {
// If there is an active process on Case object that invokes the
// BitlyShortenURLInvocable as outlined in my blog post
// https://douglascayers.wordpress.com/2015/10/21/salesforce-create-short-urls-with-bitly-process-builder-and-apex/
// then simply inserting the record will cause the code to run and ensure code coverage.
// Otherwise, the other test method is sufficient.

@IsTest
static void test_shorten2() {
// This test just ensures the invocable class will run.
// If we were to have an active process or trigger then
// inserting the record would be sufficient, as in the above test method.
// If not, then this method will be sufficient for code coverage.
//
// However, do note that trying to do both in the same test will fail.
// Trying to insert a record and call the invocable class will fail
// because the invocable class calls a @Future method that makes an HttpCallout.
// DML operations don't mix with HttpCallouts due to uncommitted work:
// "System.CalloutException: You have uncommitted work pending. Please commit or rollback before calling out.""
Test.startTest();

Hi Douglas:

Thanks for this awesome piece of code. I could make my bitly thing working, using a process builder. My bitly field is on Opportunity. However my test method fails in static void test_shorten() in BitlyShortenURLInvocableTest . It throws the following error:

System.CalloutException: You have uncommitted work pending. Please commit or rollback before calling out
Class.BitlyService.getAccessToken: line 56, column 1
Class.BitlyService.: line 12, column 1
Class.ShortURLInvoc.shortenAsync: line 25, column 1

My code in test_shorten is given below.

    Test.startTest();
    Test.setMock( HttpCalloutMock.class, new MockHttpResponse() );
    
    Opportunity job = new Opportunity();
    job.Name = 'Test Job';
    job.StageName = 'Not yet started';
    job.CloseDate = System.today() ; 
    insert job;
    Test.stopTest();
      
      
    job  = [ SELECT id, Shortened_Url__c FROM Opportunity WHERE id = :job.id LIMIT 1 ];
    
    System.assert( String.isNotBlank( job.Shortened_Url__c ) );
