Parallel Execution - A Revolution In Data Testing

When multiple operating systems run through a single database, it is called parallel execution. Checking each module separately takes time and reduces the efficiency of the software. In sequential testing, each module is tested one after another, even if the testers use multiple browsers. Parallel browsing uses numerous devices to test multiple codes and sections of data to improve the efficiency of the quality assurance process.

‍

In the past, quality assurance experts used sequential execution to test the validity of a code. The process of sequential execution entails that a single device is used to complete all the tests on the data. This process takes a lot of time and wastes the precious working hours of a coding company. Parallel execution is an alternative that provides a quick and easy solution for data and code testing as well as execution.

How Does Parallel Execution Work?

Parallel execution saves time by simultaneously testing and developing modules. An auto-defined XML file creates a set of parallel attributes. These attributes include threads, methods, instances, and classes. Here are a few ways parallel execution facilitates developers and QA personnel alike:

‍

Execution Of Code

Parallel Execution helps developers break down extensive data and divide them into small sections. These sections are analyzed side by side. These sections of code are executed side by side. As a result, the execution of the code is carried out in a short time compared to the execution of a single long line of code. 

‍
‍Analyzing Vast Amounts Of Data

Parallel execution helps you manage vast amounts of data quickly and efficiently. When you are executing operations and retrieving files at the same time, it can take days as well as weeks. With parallel execution, you can select, retrieve and divide the information in the data in more than one operating system. These combined data processing saves your time, and you can move on to other tasks in the meantime. 

Parallel Execution In Testing

When a developer runs two or more tests on a code or data simultaneously, it is called parallel execution in testing. Most developers use an automated system to run multiple tests on multiple devices and operating systems. If you want to run 50 tests that take 5 hours on separate operating systems, you can reduce the time by running them on five different devices, reducing the time to one hour. 

‍

Saves Time

Instead of using a single device or browser, the process of parallel testing execution divides the workload according to the number of tests. If there are three tests, parallel execution will use three browsers, and all these browsers will produce the results at the same time. It means that if you start 20 tests in parallel execution and have two hours to get their result, parallel execution will use 20 devices to produce the results at the end of the two hours.

Creating Order In the Data

Separating numbers and placing them in tables and indexes is like finding a needle in a haystack. Parallel execution sifts through the data and creates indexes quickly. You can use parallel execution to make queries. It enables you to form table scans and create partitioned indexed scans and joins.

‍

Instead of reading through the whole data to create one index, you can use parallel execution to build extensive indexes with an automated tool. If there are any errors in the code and you need to remove large chunks, then parallel execution is the answer. It allows you to delete as many sections as you need in minutes. You can also get updates, merge, and insert data in bulk using parallel execution. 

Parallel Execution In Selenium

Parallel execution is carried out through various tools. One of the best tools used to automate parallel execution is Selenium. It is an open-source automation tool used by organizations all across the globe to reduce their testing time. 

‍

Diverse Coding Languages

Most developers are experts in one coding language and cannot change their whole code just to run it through a tool. That is why Selenium offers the opportunity to write any code you want and tests it according to your requirements. Selenium is compatible with all the major coding languages, including Perl, C#, Java, Ruby, Python, and JavaScript. It enables developers to write code in any language they want through Selenium. 

‍

Compatibility With Diverse Browsers

Selenium is designed to run with all types of browsers. Since Selenium is used for software, you can do quality assurance and coding on any browser. That is why it is adaptable to all types of browsers, including:

• Mozilla Firefox
• Chrome
• Edge
• Safari
• Opera
• Brave browser by using chrome driver.

Conclusion

Parallel execution is the next level in quality assurance, especially regarding coding. The quality assurance teams spend significant time going through the bugs in a code. With parallel execution, they can significantly reduce the time spent on testing and focus their energies on building new programs. Selenium makes the parallel execution process more accessible by automating and providing results in the nick of time.
