Test Case Prioritization Techniques (2024)

FAQs

What is the best way to set priority for test cases in testing? ›

Test case prioritization is the process of ranking test cases based on their importance or risk. This helps to ensure that the most important test cases are executed first, and that the limited testing resources are used effectively.

Non-Essential Features

Not all features require extensive automated testing. Non-essential or rarely used features may not be a priority for automation and can be adequately covered through manual testing.

When we have multiple test cases and want to execute them in a particular order, the TestNG priority attribute helps in executing the test cases in that order. The test cases get executed in ascending order of the priority list. Thus, test cases with lower priority get executed first.

Cases that affect critical business processes or functionalities should be given higher priority. Identify the risk associated with each functionality being tested. Test cases covering high-risk features that could cause significant failures or issues should be prioritized.

Answer: Unit>>Integration>>System testing. Solution: Unit Testing: Unit testing is performed by the developer to verify the source code of all individual units or module of the application. Integration Testing: Integration testing is performed by the developer or tester.

A prioritization technique helps you make informed decisions about the order you should complete your tasks based on different factors like their importance and due dates. With a list of prioritized tasks in hand, you have a shield to respectfully push back against unnecessary meeting invites and last-minute requests.

The testing engineer basically decides a defect's severity level. The product manager basically decides a defect's priority level. There are 5 types of Severities: Cosmetic, Minor, Moderate, Major, and Critical. There are 3 types of Priorities: High, Medium, and Low.

The MoSCoW method is a versatile prioritization tool. For personal tasks or everyday to-do lists, it helps individuals zero in on what's essential, ensuring they don't waste time on low-priority activities.

What are the 2 most important factors to consider when prioritizing risk? ›

Risk matrices are sorted by probability x impact. The higher the probability of a risk — and the higher the impact — means the subsequent risk response priority will be higher.

Ad-hoc Testing

It is informal/unstructured that does not follow any testing pattern to find defects that might have been missed in traditional testing. You cannot automate them because it is difficult to categorize the test cases.

How do you prioritize tasks effectively? Start by creating a comprehensive task list and identifying deadlines. Assess the importance, urgency, effort, and resources required for each one. Then prioritize your list based on the most urgent tasks, considering dependencies and breaking down complex tasks if necessary.

You might say this:

At the beginning of each workday, I write down the tasks that need to be done and rank them from highest to lowest priority. Not only does this help my workflow, but it also ensures that I am making progress on the most important tasks of the day.”

High Priority

Bugs that require immediate attention and resolution because they impact critical functionality or pose significant risks fall under this category. For example, if an online ticket booking system fails to generate tickets after successful payment, it would be assigned a HIGH priority.
