Working with JSON POJO Classes in Selenium Java

Introduction:

In the world of Selenium automation with Java, dealing with JSON data is a common scenario. Often, we need to interact with APIs or read JSON responses from web services. To handle JSON data effectively, one powerful approach is to use Plain Old Java Object (POJO) classes. In this blog post, we'll explore how to create and work with JSON POJO classes to extract program details, including name, description, and status, from JSON data in your Selenium Java automation scripts.

Why Use JSON POJO Classes:

JSON POJO classes serve as a bridge between JSON data and Java objects. They provide a structured way to map JSON data to Java objects, making it easier to manipulate, validate, and interact with JSON responses in your Selenium automation scripts.

Scenario: Extracting Program Details from JSON Data

Imagine you have a JSON response from a web service representing program details with name, description and status and use them in your Selenium automation script.

Creating JSON POJO Classes:

To start, create a JSON POJO class that matches the JSON structure.

In this case, we'll create a ProgramPOJO class:

Mapping JSON to POJO:

Next, we need to map the JSON data to your ProgramPOJO class.

In this case, we'll create a JsonFileReader class:

Here's how you can do it in your Selenium step definition to get the values:

Benefits of Using JSON POJO Classes:

1. Structured Data: POJO classes provide a structured representation of JSON data, making your code more organized and readable.

2. Ease of Use: Mapping JSON to POJO objects is straightforward, simplifying the handling of JSON data in your scripts.

3. Code Reusability: You can reuse these classes across your test suite, promoting modularity and maintainability.

4. Type Safety: POJO classes offer type safety, reducing the risk of runtime errors when accessing JSON data.

Conclusion:

Leveraging JSON POJO classes in Selenium Java scripts allows you to efficiently handle and extract data from JSON responses. In this example, we demonstrated how to create a ProgramPOJO class and use it to extract program details (name, description, and status) from JSON data in your Selenium step definition. This approach enhances code readability, maintainability, and reusability, making your automation scripts more efficient and robust when dealing with JSON data.
