Ambiguous questions on tests

Will writing the test slow the coding cycle

• In the short term, It will slow us down and in the long term, it will make coding faster in maintaining the code.
• Since setting up the test suite is time-consuming.
• Maintaining the code becomes a lot easier.
• We can run hundreds of test cases instantly without a delay.

When to write which types of tests

• We need to structure our code in such a way that business logic has pure Java/kotlin code and does not involve Android dependencies. If this is organized in this way we can use J-unit tests for this purpose.
• If the Android framework is involved, we might need instrumentation tests that require a device or an emulator.
