  • Experience in working with Excel, Property files, POJO in Java is preferred


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 !

Hi All,

My name is Amuthan Sakthivel. I work as a Senior Test Automation Engineer in a Private Company. I have started my career as a Manual Tester but slowly picked up Automation Testing along the way.

I know how hard it is to transform from a Manual Tester to SDET and that’s the reason I want to make this transformation easier with my tutorials. So, I write to code like a beginner, then improvise it a little, then optimize a little to make it cleaner.

I still strive to learn and continuously improvise every day. This attitude has helped me to learn lot of technologies and tools related to Test Automation.

I have worked on multiple tools in Java stack like Selenium, Appium, Rest Assured, Postman, SoapUI, Jenkins, Docker, Microservices, Openshift and AWS to name a few. I have automated 30+ applications, tailoring all of them from scratch.

I take Corporate Training and online training courses apart from creating content on Youtube.

I am a passionate Cricket Player and play it regularly :)
