Fast quality is the new mantra of most CIOs. In response, Development Operations has evolved its software life cycle-becoming more agile and more scalable, while trying to provide a perfect experience. In response, companies continue to provide consumers with new products and updates, and their reliance on slow and complex testing processes limits their speed in delivering high-quality code and features. The rapid pace of change directly affects the functional testing space. How to deliver products quickly while maintaining the highest experience standards?
Enter parallel test.
Parallelization is not a process of running a single test at the same time, but a process of running multiple automated test cases in parallel. With parallel testing, organizations can greatly save the time required to perform automated testing while greatly improving the scope and scale of the testing.
ROI is instant and can be easily quantified because there is a direct correlation between the number of concurrent executions and the time it takes to run the test suite. For example, suppose a team has 100 automated test suites, and each test takes an average of one minute to execute. If executed sequentially, it means that the test suite takes 100 minutes to run. However, if the team distributes the test suite in 10 parallel environments running at the same time, they can reduce the execution time by a factor of ten, to a total of 10 minutes. This results in a lot of time being reinvested in the hands of developers.

Improve liquidity during development
More and more DevOps teams are adopting continuous integration and continuous delivery processes, which require frequent and reliable functional testing. A development team that can get test results faster can maintain a more constant code writing, test process, and repeat all of these tasks as quickly as possible.
Implementing a parallel testing process can optimize this continuous process. Getting results quickly is a core part of CI/CD, because the sooner developers do it, the sooner they start debugging, refactoring or putting into production. In addition, organizations can reduce costs and improve accessibility by migrating test environments to the cloud.
Use the CrossBrowserTesting Jenkins plugin to execute the sample code executed in the Jenkins pipeline in NodeJS. The plug-in allows users to specify the required environment configuration separately from the test framework in the pipeline itself to increase flexibility.
Greatly reduce test costs
By running parallel tests on virtual machines in a cloud environment, you can greatly reduce the cost of each test. Working with partners such as SmartBear-providing more combinations of virtual machines and real devices in public and private cloud environments-helps reduce the burden of maintaining test environments and equipment, which is expensive. Parallel testing is a way to utilize all these browser combinations and devices. Speaking of...
Significantly increase test coverage
Because parallel testing is faster-and you can access thousands of device and browser combinations in SmartBear's public cloud-your team can ensure that the scope of testing is even wider. If your customers are a diverse group that spans various mobile devices and have their own preferred operating system and browser, you need to make sure that the code you push covers all these basics. Dissatisfied users using edge protection devices or browser types may be enough to damage your business’s reputation. With parallel testing, you are more likely to avoid this situation.
Changing from sequential testing or manual testing to an automated testing environment with multiple parallel items may be intimidating for some teams, but it is not necessarily frightening! You can take some simple steps, first increase to two parallel tests, then perform some automated tests here, and then continue to expand. SmartBear is here to help you explore the many benefits of parallel testing.
The above are some video resources I collected, which helped me a lot in this process. If you don't want to experience the feeling that you can't find the information during self-study, no one answers your questions, and insists on giving up after a few days, you can join our deduction group [313782132], which has various software testing resources and technical discussions.
Finally: Welcome to follow the editor to receive a summary of the core knowledge of Python automated test engineers with a 300-page pdf document! Software testing technology exchange group: (313782132) The content of these materials are all the knowledge points that the interviewer must ask during the interview. The chapter includes many knowledge points, including basic knowledge, Linux essentials, Shell, Internet program principles, Mysql Database, package capture tool topics, interface testing tools, advanced testing-Python programming, Web automation testing, APP automation testing, interface automation testing, advanced continuous integration testing, testing architecture development testing framework, performance testing, security testing, etc.
