Unlocking the Power of Web Robots with XPath: A Practical Guide

In today’s fast-paced digital landscape, the need for accurate and fast data gathering has become essential across industries. Enter web robots (or web scrapers), which automate the process of extracting data from websites. At the core of efficient web robots is XPath (XML Path Language), a powerful syntax used to navigate and identify specific elements on a webpage.

Comprehensive Guide to API Testing Using Postman

APIs (Application Programming Interfaces) are the backbone of modern web and mobile applications, enabling data exchange between applications, services, and users. As a tester, ensuring the reliability, functionality, and performance of APIs is crucial. Postman, a powerful API testing tool, has become the go-to for testers due to its user-friendly interface and robust capabilities. In this guide, we’ll dive into API testing using Postman, covering the fundamentals, setup, types of testing, and some best practices.

Tips to build your test data

Let us see the different types of test data:

Test data types

a. Application configuration data

Your application likely needs test data to function (or even launch). Examples of application configuration data include the information to connect to database(s), admin user name and password and server information (e.g. email server) in order to send email notifications.

What types of testing should you perform?

There are many kinds of testing that one hears about. You would likely know about many types of testing e.g. white box testing and black box testing, unit testing, integration testing, system testing, system integration testing and so on. The types of testing that would be performed on the application are usually identified in the test planning phase. If you wish to know which kinds of testing are suitable in your project, consider the following questions:

Sample database test plan

Here are some tips to create a good database test plan:

1. Database testing can get complex. It may be worth your while if you create a separate test plan specifically for database testing.

Regression testing

First, the basics. The term "regression" is used to describe the decay, weakening or degeneration of software. Software is modified to add enhancements to it, fix known defects, make performance improvements, make the code more maintainable or make the code compliant to patterns. But, software can regress when it is modified. This can happen in a number of ways:

a. The faulty design is re-used to create an enhancement

How to test software without any requirements?

You have been handed an application with no requirements. You are supposed to test it. Can you do it? Sure, you can. Check the following behaviors first.

• Does the application launch?
• Does the application have a help/ demo file? You can find abundant information in the help/ demo file to help you design your test cases.
