TIP: Please make sure to read Getting started with programming tasks first.
You can start with our sample project that can be found on GitHub:
Any project which uses xcodebuild can be used as a programming task. We use tests to execute unit tests.
Your project will be executed with following command:
xcodebuild -scheme Devskiller -destination 'platform=iOS Simulator,name=iPhone 11 Pro Max' clean test
It is possible to automatically assess the solution posted by the candidate. Automatic assessment is based on unit test results and code quality measurements.
There are two kinds of unit tests:
- Candidate tests - unit tests that the candidate can see during the test should be used only for basic verification and to guide the candidate in understanding the requirements of the project. Candidate tests WILL NOT be used to calculate the final score.
- Verification tests - unit tests that the candidate can’t see during the test. Files containing verification tests will be added to the project after the candidate finishes the test and will be executed during the verification phase. The results of the verification tests will be used to calculate the final score.
Once the solution is developed and submitted, the platform executes verification tests and performs static code analysis.
Devskiller project descriptor
Programming tasks can be configured with the Devskiller project descriptor file:
- Create a
- Place it in the root directory of your project.
Here is an example project descriptor:
You can find more details about the
devskiller.json descriptor in our documentation.
Automatic verification with verification tests
The solution submitted by the candidate may be verified using automated tests. You’ll just have to define which tests should be treated as verification tests.
All files classified as verification tests will be removed from the project prior to inviting the candidate.
To define verification tests, you need to set two configuration properties in
testNamePatterns- an array of RegEx patterns that should match all the names of the verification tests.
pathPatterns- an array of GLOB patterns which should match all the files containing verification tests. All the files that match defined patterns will be deleted from candidates' projects and will be added to the projects during the verification phase. These files will not be visible to the candidate during the test.
In our sample project all verification tests are in the
CalculatorVerifyTests class and the class is located in file which names contains
CalculatorTests/verify_pack. In this case the following patterns will be sufficient:
"testNamePatterns": [".*VerifyTests.*"], "pathPatterns": ["**CalculatorTests/verify_pack**"]
