Having in mind that every class and method in your code will need to be tested, this can impact your ability as a developer to ship new features Increased overhead of amount of code to write. However, there are pros and cons on using both (that mostly depends on the organization, engineer in charge of creating one type or all of them).Įasy to create (taking for granted that the code is of high quality standards and unit testing "friendly")īetter understanding of the code (by unit testing your code you may reveal cases you did not anticipate and will help you define the a better behavior of the code)Ĭan catch high severity or show stopper bugs Judging by the above statement, I'd say you need to have both unit tests and UI automated tests (or integration as well depending on the architecture layer and systems integrated). Info: These testcases are critical functionality. If your applications don't use a database or external data store but rely on live communication things get much more complex - I wouldn't try to offer suggestions on that without more information about how your application architecture is configured. This is the method I use to deal with testing across multiple applications regardless of what they're running on or what automation framework I'm using. With database validation as part of your tests, you know that the Frank tests have successfully sent data, and you can then use a database with that data as the baseline for your web application tests. You're checking the data in your database after the test (or tests) are complete. You're starting your web and ios tests with a known database state,
If you're using a database - or any other kind of external data store - you don't need to do unified testing if these circumstances apply: I've found that simulation often has crucial differences from actual input.įor automation, the crucial question here is where the data sent from the ios app is stored.

This is the kind of scenario where I'd use a mix of automated and manual testing - manual testing using the iPad, because one thing GUI automation always does is simulate the human inputs.
Your decision should never be made alone, please coordinate with the rest of your team before making a decision that may impact others and mostly importantly, the overall progress of a project. Please remember a tester is an integral part of a multi-discipline, cross-fucntional team. To which extend, you will implement negative tests? The number of negative tests is infinite, so you will have to limit the number of -ve tests and you need to show why you have chosen some -ve tests and not others. What are the consequenses of not having -ve tests? How much extra effort / time do you require in order to implement +ve and -ve tests? Some of aspects you may need to take into account include but not limited to: You may need to present the pros and cons to your product owner to help him / her make this decision. Your product owner (aka stake holder) will be interested in listening to your reason for having positive tests and negative tests or not. The only tool I can have personally used is pact-jvm The producer test should use the real producer application with a simulated consumer to test that the producer behaves as the consumer expects. The consumer test should use the real consumer application with a simulated producer to test that the consumer behaves correctly when the producer behaves as the consumer expects You need to be confident that each time an application is built, it can be safely released, whether it is released first or last into production relative to the application it is a consumer/producer for. You are missing that you need to verify more than just Latest A and Latest B if you want to be able to deploy A and B independently. This test is run against the following version combinations: The producer test uses the consumer contract file of B to verify that A behaves as B expects it to. B will contain a consumer test that produces this file and checks that B behaves correctly when it receives these expected responses from A.Įach time B builds, it publishes the contract file and triggers an "A to B producer test". The consumer B produces a "B to A consumer contract file" that contains example requests and responses that it expects from A. Here is how I have seen this implemented before:
