Must know Java Libraries – SDET Essentials

Java has a lot of amazing external libraries which can help us to write clean code. I have covered 4 of those amazing libraries in detail and how to use them in real-time projects.

1. Owner – To resolve the problems we face while reading property files.

Owner Library can help to reduce all the boilerplate code we write while reading property files. No need to do Exception Handling. It comes bundled with some amazing features like DefaultValue on missing attributes, Key Annotation for Mapping, and much more.

2. Zerocell – To resolve the problems we face while reading the excel sheet. Excel Reading – No more a pain

We normally use the Apache poi library for Excel Reading in Java. However, we need to write a lot of code to get the work done. Working with different data types like Integer, dates, and comma-separated strings in excel is again a big problem. Zero cells provide a solution for all the boilerplate codes we write.

Reusable Converter classes help us to maintain the business logic away from tests.

3. Fixture Factory – Generate POJO’s for you rest assured tests using Template – Easy and Fast.

We normally generate POJOs for testing rest services. However, we spend so much time passing the values to the POJO fields. Fixture Factory helps us to create objects based on templates and can create thousands of objects on the fly.

4. Lombok – Say Good Bye to Verbosity.

Implement these libraries in your company and stun your colleagues!
