Software Testing

Testing:

The process of testing involves running a program to look for errors. The software must be error-free to function properly. The software will be free of all errors if testing is successful.

Guidelines for Testing:

• The client requirements should be met by all testing.
• software should be tested by a third party.
• It is not possible to conduct elaborative testing. Because we need the least amount of testing possible based on the application’s risk assessment.
• All tests should be planned before they are carried out.
• Test small parts first, then progress to larger parts.

Types of testing:

• Manual Testing
• Automatic Testing

Manual Testing:

Manual testing is a method of software testing in which test cases are executed manually rather than using an automated tool. Manual testing is one of the most fundamental testing processes because it can trace both visible and hidden software defects. All test cases are manually executed by the tester from the perspective of the end user. Test case reports are manually created.

Types of Manual Testing

o          White Box Testing – Developers perform white box testing, which involves checking every line of code before passing it to the Test Engineer. Because the code is visible to the developer during testing, it is also known as white box testing.

o          Black Box Testing – The Test Engineer performs black box testing to ensure that an application or software meets the needs of the customer or client. The code is not visible while testing, which is why it is referred to as black-box testing.

o          Gray Box Testing – Gray box testing is a hybrid of white box and black box testing methods. It can be done by someone who is familiar with both coding and testing. Gray box testing is used when a single person performs both white box and black box testing for an application.

Why is Manual Testing preferred?

• It doesn’t require any programming knowledge and easy to learn for new testers.
• It ensures that the software is a hundred percent bug-free and a cost-effective method
• It is used to test GUI designs that change dynamically
• The Tester interacts with software as a real user

Drawbacks of Manual Testing:

• It generally requires a large amount of human resources and a very time consuming method.
• It does not test for all aspects of testing.

Automatic Testing

Automated testing is a technique in which the tester writes their own scripts and uses appropriate software or an automation tool to test the software.

It is a manual process that has been automated. It Allows repetitive tasks to be completed without the intervention of a Manual Tester.

Automation Testing Process:

Some Popular Automation Tools are Selenium, QTP, TestNG, etc

Advantages of Automation Testing:

• Simplifies the execution of test cases
• Increases the Reliability of Tests
• Minimizes Human Interaction
• It saves both time and money.
• increases the number of tests covered

Selenium automation testing:

Selenium is a free (open source), popular automated web application testing framework. It is a browser-based automation framework that simulates and automates user actions. Selenium is a collection of tools that serve a variety of Selenium automation testing needs. Selenium automation testing is a test that is run using the Selenium framework.

Selenium Test Scripts can be written in a variety of programming languages, including Java, C#, and Python.

Selenium is simple to install on platforms such as Windows, Linux, Solaris, and Macintosh. Furthermore, it supports operating systems (OS) for mobile applications such as iOS, Windows Mobile, and Android.

Selenium supports Internet Explorer, Mozilla Firefox, Google Chrome, and Safari browsers.

Selenium can be used to automate functional tests and is compatible with automation testing tools like Maven, Jenkins, and Docker to achieve continuous testing. It can also be used in conjunction with tools like TestNG and JUnit to manage test cases and generate reports.
