Four Libraries That Cut Java Boilerplate
This course covers four external Java libraries that solve recurring pain points in test automation: Owner for reading property files without manual exception handling, Zerocell for reading Excel sheets, Fixture Factory for generating POJOs from templates, and Lombok for reducing verbosity.
Who it's for: SDETs and test automation engineers already comfortable with Java who want to write cleaner, less repetitive code.
Key Takeaways
- Using Owner to eliminate boilerplate property-file reading, with default values and key mapping
- Reading Excel data reliably with Zerocell instead of raw Apache POI
- Generating large volumes of test POJOs from templates with Fixture Factory
- Reducing verbosity in Java classes with Lombok
Each library is covered in enough depth to apply directly in real test projects, with reusable converter classes for keeping business logic out of tests.
About this course
Java have 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 boiler plate 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 excel sheet. Excel Reading - No more a pain
We normally use Apache poi library for Excel Reading in Java. However we need to write lot of code to get the work done. Working with different data types like Integer, date, comma separated string in excel is again a big problem. Zero cell provides solution for all the boiler plate code we write.
Reusable Converter classes helps 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 POJO's for testing rest services. However we spend so much of time in passing the values to the POJO fields. Fixture Factory helps us to create objects based on template and can create 1000's of objects on the fly.
4. Lombok - Say Good Bye to Verbosity.
Implement these libraries in your company and stun your colleagues !
