Tests TLDR Versions

Smoke Tests: These test cases are executed to check if the critical functionalities of the program are working fine.

They can be further broken down into 3 types:-

1. Unit/Component Testing: Checks if individual components or functions work the way as expected.
2. Integration Testing: Checks if the components work with each other as expected.
3. End-to-End Testing: A complete application test to check if the application works as expected.

Performance Tests: A performance test is any test that measures performance, stability, scalability and/or throughput of an application.

They can be further broken down into 5 types:-

1. Load Testing: Tests if the application can handle expected normal and peak load.
2. Soak/Reliability Testing: A soak test is a long-running load test used to determine application performance and stability over time.
3. Stress Testing: Checks behavior of applications above peak load conditions.
4. Capacity Testing: Capacity Test determines the number of users app can handle before either performance or stability becomes unacceptable.
5. Spike Testing: Verify system stability during bursts of concurrent users or system activity.

Authors note:

There are many different kinds of tests that I haven't included related to design, security and some I am not even aware of. I have included only the ones I think are related to development in TLDR format.
This was my first post, please leave your feedback. Also, let me know if I have made any mistakes.
