Have you ever visited a website that only has plain text and images? Most probably, no. It’s because such websites do not exist now. But there was a time when websites only had plain text and images with almost no styling. For the longest time, websites did not focus on user experience. For instance, this is how eBay’s homepage looked in 1999.
Pair testing can help you complete your testing tasks faster and with higher quality. But who can do pair testing, and when should it be done? And what form of pair testing is best for your circumstance? Check out this blog for more information on how to conduct pair testing to optimize its benefits.
Continuous integration is a coding philosophy and set of practices that encourage development teams to make small code changes and check them into a version control repository regularly. Most modern applications necessitate the development of code across multiple platforms and tools, so teams require a consistent mechanism for integrating and validating changes. Continuous integration creates an automated way for developers to build, package, and test their applications. A consistent integration process encourages developers to commit code changes more frequently, resulting in improved collaboration and code quality.
Greetings folks! With the new year finally upon us, we’re excited to announce a collection of brand-new product updates. At LambdaTest, we strive to provide you with a comprehensive test orchestration and execution platform to ensure the ultimate web and mobile experience.
Development practices are constantly changing and as testers, we need to embrace change. One of the changes that we can experience is the move from monthly or quarterly releases to continuous delivery or continuous deployment. This move to continuous delivery or deployment offers testers the chance to learn new skills.
Learn to execute automation testing from scratch with LambdaTest Learning Hub. Right from setting up the prerequisites to run your first automation test, to following best practices and diving deeper into advanced test scenarios. LambdaTest Learning Hubs compile a list of step-by-step guides to help you be proficient with different test automation frameworks i.e. Selenium, Cypress, TestNG etc.
You could also refer to video tutorials over LambdaTest YouTube channel to get step by step demonstration from industry experts.
Execute automation tests with cpu_power_management on a cloud-based Grid of 3000+ real browsers and operating systems for both web and mobile applications.
