Join Mark DiFranco for an in-depth discussion in this video Next steps, part of Swift: Writing Testable Code.
- [Mark] We're at the end of our course…on writing testable code in Swift.…Hopefully you've been inspired to start adding tests…to you projects.…We've covered the dependency inversion principle…and the single responsibility principle,…and we've seen how they can help us keep our architecture…flexible and easy to use.…We then took a look at some best practices…when writing unit tests.…Finally we wrote some UI tests…to test the user interface of our app.…If you're planning on starting a new project soon,…I recommend trying to use the concepts…covered in this course.…It's almost guaranteed to save you…some headaches down the road.…
If you've already got an existing project,…you can still integrate these concepts.…I recommend starting with your lower level classes…and building up from there.…Make your assembler a singleton…and manually resolve dependencies in the classes…that have not been converted yet…similar to how the AppDelegate works in our sample project.…Swinject has a few other frameworks available…to help us with dependency injection,…
