Options for Manual Test Case Development & Management

The purpose of developing test cases is to ensure the application functions as expected for the customer. Test cases provide basic application documentation for every function, feature, and integrated connection. Test case development often detects defects in the design or missing requirements early in the development process. Additionally, well-written test cases provide internal documentation for all application processing. Test case development is an important part of determining software quality and keeping defects away from customers.

Top 17 Resources To Learn Test Automation

Lack of training is something that creates a major roadblock for a tester. Often, testers working in an organization are all of a sudden forced to learn a new framework or an automation tool whenever a new project demands it. You may be overwhelmed on how to learn test automation, where to start from and how to master test automation for web applications, and mobile applications on a new technology so soon.

13 Best Test Automation Frameworks: The 2021 List

Automation frameworks enable automation testers by simplifying the test development and execution activities. A typical automation framework provides an environment for executing test plans and generating repeatable output. They are specialized tools that assist you in your everyday test automation tasks. Whether it is a test runner, an action recording tool, or a web testing tool, it is there to remove all the hard work from building test scripts and leave you with more time to do quality checks. Test Automation is a proven, cost-effective approach to improving software development. Therefore, choosing the best test automation framework can prove crucial to your test results and QA timeframes.

How to Position Your Team for Success in Estimation

Estimates are critical if you want to be successful with projects. If you begin with a bad estimating approach, the project will almost certainly fail. To produce a much more promising estimate, direct each estimation-process issue toward a repeatable standard process. A smart approach reduces the degree of uncertainty. When dealing with presales phases, having the most precise estimation findings can assist you to deal with the project plan. This also helps the process to function more successfully, especially when faced with tight schedules and the danger of deviation.
