Web Testing Complete Guide Image

Website testing means the process of checking your website for potential bugs and errors before taking it online and live for the digital public. It helps in addressing issues like functionality, usability, compatibility, reliability, and security. One of the major reasons for testing a website is to abide by the laws of web accessibility. There are more than 4 billion users of the internet in the world. Everything has been summarized right in the palm of our hands. Data spread faster than bush fire now. To stand out and make sure there are no miseries left, website checkers exist. Before we start the complete website testing guide, we explain what web testing entails.

Web testing explained

The origin of testing came from the Chinese to select the best candidates for their government. In technology and the internet, testing became essential since IBM revolutionized the technology with its personal computers. 

Several software and websites came in. PCs were introduced in the market with different specifications. These differences were a problem for the programs to run the same on all the devices. Errors were popping up, and they had to be addressed by testing and correcting method. 

There is always a chance of human error when creating a program. Testing provides assurance that the work done is error-free and efficient.

Importance of website testing: a complete guide

The significance of website testing has increased like never, so we felt it was time for a complete guide. Web testing gives you insight, highlights, or offers to remove issues that can decrease website ranking and break its backlinking. Issues like long loading time, forms that do not submit, and broken links can frustrate the users. 

More than half of Google searches (56%) happen on mobile devices. A well-tested website will adjust itself with distinct screen sizes and devices with different specifications. As a result, your website will achieve compatibility. This will also reduce the cost of redesigning the website every time it is updated. On top of all, testing websites will also ensure compliance with the web accessibility laws and requirements.

Challenges with website testing

Testing a website is not as easy as it seems. There are a lot of challenges that come up, especially at the development stage. 

The first challenge is to make sure that the website is complying with the integration testing. This can be done by putting yourself in the shoes of the users. It is the overall checkup that the website is usable and functional in all aspects and does not collapse after merging new features.

Another challenge is to check the performance of your website. Whether large applications run smoothly on minimal hardware or not, try loading your site on low internet speed and bandwidth. The significance of testing this phase is of supreme importance. 

Evaluating the security of your website is also an obstacle. Check your website for viruses and see if they redirect correctly for 3rd party websites. An example of such a website is 3rd party secure payment pages.

Other general problems that might occur while testing include:

  • Not having a proper strategy set due to lack of knowledge.
  • Not selecting the right testing tools which lead to wastage of time due to repetition.
  • Being low on resources such as time and budget.
  • Testing everything right but poor analysis of resulted errors. This challenge requires experienced persons to reach conclusions and correct the issues that came up as a result of testing.

Best Web Testing Strategy – a Complete Guide

So far, we have looked at how monumental the importance is to test a website before taking it live. Here is the complete guide on how testing your website can be done correctly with the following tests.

• Functionality testing

It is a process of testing that assesses the framework of a website. This includes checking if any of the links are broken. These links include outgoing links, incoming links, links that move on the same page, links leading to mail, etc.

This process also deals with testing forms, which covers checking if an error message is displayed when wrong input is made by the user. An example of incorrect input includes leaving out mandatory fields in forms.

Further, whether they are deleted or not after the cache is cleared or when the cookies are expired, testing cookies are also part of this testing process. 

• Usability testing

Usability testing involves measuring the usability and interaction of users with the website to identify the weak points. This includes testing for navigation, i.e., what methods are available for users to surf around using different forms of input. 

Another important area it tests is how the content is presented and whether it is accessible to every user or not? A hidden benefit of testing for usability is it covers most of the compliance requirements for web accessibility laws.

• Interface testing 

Interface testing covers testing of an application server, database server, and web server. Interaction between these servers should be executed, and errors should be handled effectively.

• Compatibility testing

This test ensures that your website is compatible with all the devices and works accurately across different devices. Compatibility testing includes evaluating cross-browser and OS compatibility. 

These checks can be performed by loading your website on several browsers and operating systems with different versions. This will give assurance on the error-free working of the website.

• Performance testing

The performance of a website can be tested by accessing through many devices at the same time. A good-tested website will run smoothly even with a huge number of users. Also, doing a load test on low internet speed and different connection types will evaluate its status.

• Security testing

Security is one of the most important areas to test when developing a website. There is a great possibility that the data is leaked from the website. This data includes customer bank card details, which could result in huge losses. Furthermore, getting affected by viruses is also a great risk for the websites.

Once you have gathered info, planned tests, and scenarios, it is time to execute the testing strategy by doing the tests mentioned above. After testing your website, analyze the result of these tests. Find the weaknesses and try to solve the loopholes. When you are done with everything, it is advised to test again for confirmation before launching it to the general public.

Ways of web testing

Websites can be tested in a number of ways. Some common ways of testing are:

• Random testing

Random testing means getting your website tested by random users who evaluate the usability defects of the website. This method saves cost as hiring experts for this job could be expensive.

• Expert testing

Experts test the website by going deep into different levels of penetration based on your budget and flexibility. This method might be costly but does a very extensive job to get the best results possible.

• Mobile testing

Some websites are specifically designed for mobile devices. They have special mobile-based widgets and stickers. In this method, testing the compatibility feature of your website is highly important.

Self-testing or outsourcing?

The answer to this question depends on how much value you want to add to your testing strategy. Outsource when the frequency of testing your websites is not very high. If you have to test only once or twice, outsourcing is the right option to do as it will be cost-effective.

Having an in-house department for testing would only be beneficial when an evaluation is recurring. It might raise some costs, but you will have a dedicated segment to ensure your services.

Website testing options

There are two website testing options. One is automated testing, and the other is manual testing. Automated testing is done through designing tests by writing programs and executing them at will. This saves time as it runs several different configurations at the same time. The problem with this testing is it can be repetitive when you update the website as the whole test program will run again.

Manual testing can be done by making your strategy to test the features of the websites. These include functionality tests, usability tests, security tests, interface tests, compatibility tests, and performance tests, which are discussed above.

The best option is to select a hybrid mode of testing which involves both methods. This can be done by running an automated test first, followed by manual testing to go deep into the areas that show errors. In some cases where automated testing fails, manual testing will be compulsory. By using both simultaneously, the website will be tested efficiently and will produce the desired outcome.
