Manual Software Testing Pdf

[Darth Sanderson]

Whilethat may seem like simple and straightforward steps, when you factor in the number of test cases to do, and the number of times these test cases must be re-executed (known as regression tests), the amount of effort required becomes more than enormous.

Both manual testing and automation testing have their strengths and weaknesses. The choice between them depends on factors such as project size, complexity, frequency of testing, available resources, and the specific goals of testing.

In practice, a combination of both approaches often yields the best results, with manual testing for exploratory and usability aspects and automation testing for repetitive and resource-intensive tasks. You can have a look at the table below to better understand the differences between the 2 approaches:

A general rule of thumb is that test cases with higher complexity and low repetitiveness should be conducted manually to ensure that there is human input to the test, while repetitive test cases are generally automated so that testers can focus on other value-generating activities

Testing is a vast domain. When a software application is developed, it goes through various stages of testing. The types of tests may vary from functional testing to non-functional testing, subject to project/product requirements.

Unit Testing involves the verification of individual components or units of source code. A unit can be referred to as the smallest testable part of any software. It focuses on testing the functionality of individual components within the application. Developers often use it to discover bugs in the early stages of the development cycle.

A unit test case would be as fundamental as clicking a button on a web page and verifying whether it performs the desired operation. For example, you are ensuring that a share button on a webpage lets you share the correct page link.

Integration testing is the next step after unit testing. Multiple units are integrated to be tested as a whole. For example, testing a series of webpages in a particular order to verify interoperability.

This approach helps QAs evaluate how several application components work together to provide the desired result. Performing integration testing in parallel with development allows developers to detect and locate bugs faster.

As the name suggests, system testing involves testing all the integrated modules of the software as a whole. It helps QAs verify whether the system meets the desired requirements. It includes multiple tests like validating output based on specific input,

testing user experience and more.

Along with testing UI elements, UI testing must consider the various browsers, browser versions, and devices. People access the internet from various browser-device-OS combinations, meaning the UI must render and function perfectly from each. In other words, cross browser testing must be essential to any UI testing strategy.

Instead of downloading every browser version and purchasing every device your target audience uses, consider using a cloud-based testing infrastructure such as the one provided by BrowserStack.

Among other forms of acceptance testing, accessibility testing deserves special mention. Accessibility testing ensures that every feature of a website or app is easy to use by people who may have disabilities such as visual or hearing impairment, color blindness, or any other physical issues. They may experience some form of disability, requiring some form of assistive technology to operate certain technology.

Manual testing can never be avoided entirely as it is a continuous process that requires human verification at regular intervals throughout the software development lifecycle. As a result, teams need to find the right balance between manual and automated tests.

To check the accessibility of your content, it's important to use both automated tools and non-technical tests. Automated checkers such as Siteimprove, WAVE, and Axe provide efficient and thorough review of the content and underlying code, but they can't find every accessibility issue. So you'll need to do a manual review for a complete assessment. To manually test your site, review the content, test with a keyboard, and use a screen reader to make sure your website is accessible and inclusive to everyone.

Test with a screen reader to uncover issues with reading order, spelling, dynamic content, and interactive elements. While a little daunting at first, it is an essential and informative step in assessing your content for accessibility.

Manual testing is a software testing process in which test cases are executed manually without using any automated tool. All test cases executed by the tester manually according to the end user's perspective. It ensures whether the application is working, as mentioned in the requirement document or not. Test cases are planned and implemented to complete almost 100 percent of the software application. Test case reports are also generated manually.

Manual Testing is one of the most fundamental testing processes as it can find both visible and hidden defects of the software. The difference between expected output and output, given by the software, is defined as a defect. The developer fixed the defects and handed it to the tester for retesting.

Manual testing is mandatory for every newly developed software before automated testing. This testing requires great efforts and time, but it gives the surety of bug-free software. Manual Testing requires knowledge of manual testing techniques but not of any automated testing tool.

If we don't want to face these kinds of problems, we need to perform one round of testing to make the application bug free and stable and deliver a quality product to the client, because if the application is bug free, the end-user will use the application more conveniently.

If the test engineer does manual testing, he/she can test the application as an end-user perspective and get more familiar with the product, which helps them to write the correct test cases of the application and give the quick feedback of the application.

The white box testing is done by Developer, where they check every line of a code before giving it to the Test Engineer. Since the code is visible for the Developer during the testing, that's why it is also known as White box testing.

The black box testing is done by the Test Engineer, where they can check the functionality of an application or the software according to the customer /client's needs. In this, the code is not visible while performing the testing; that's why it is known as black-box testing.

Gray box testing is a combination of white box and Black box testing. It can be performed by a person who knew both coding and testing. And if the single person performs white box, as well as black-box testing for the application, is known as Gray box testing.

It is software, which is used to convert the code into application format. And it consists of some set of features and bug fixes that are handed over to the test engineer for testing purposes until it becomes stable.

As soon as the test engineer gets the bug, they will send it to the developers, and they need some time to analyze; after that, he/she only fixes the bug (Test engineer can't give the collection of bug).

The developer is decided how many bugs he can fix according to their time. And the test engineer is decided, which bug should be fixed first according to their needs because the test engineers cannot afford to stop testing.

The time will increase because at the first Build, and developers should write the code in the different features. And at the end, he/she can only do the bug fixes and the numbers of days will be decreased.

The bugs found in one build and can be fixed any of the future Build, which depends on the test engineer's requirement. Each new Build is the modified version of the old one, and these modifications could be the bug fixes or adding some new features.

In the beginning, we used to get weekly builds, but in the latest stage of testing, when the application was getting stable, we used to get the new Build once in 3 days, two days, or a daily basis as well.

In manual testing, different types of testing like unit, integration, security, performance, and bug tracking, we have various tools such as Jira, Bugzilla, Mantis, Zap, NUnit, Tessy, LoadRunner, Citrus, SonarQube, etc. available in the market. Some of the tools are open-source, and some are commercial.

Citrus is an integration testing tool, which is the most commonly used test framework. It is written in Java programming language. It is mostly used to request and respond to server-side and client-side and validate the XML JSON files.

ZAP is an open-source web application security scanner. It is stands for Zed Attack Proxy. Just like some other tools, it is also written in the JAVA programming language. It is the most effective Open Web Application Security Projects [OWASP].

It is completely written in the JAVA programming language. It offers fully automated evaluation and integration with Ant, Maven, Gradle, MSBuild, and constant integration tools. SonarQube has the ability to record a metrics history and gives the evolution graph.

Bugzilla is an open-source tool that helps the customer and the client to keep track of the defects. Bugzilla is also considered a test management tool because in this, we can easily link other test case management tools such as ALM, Quality Centre, etc.

Mantis is a web-based bug tracking system. ManitsBT stands for Mantis Bug Tracker. It is used to follow the software defects and performed in the PHP programming language. It is also an open-source tool.

Another integration testing tool is Tessy, which is used to perform the integration and unit testing for the embedded software. It also helps us to discover the code coverage of the software or an application.
