How to Accurately Estimate the Time it Takes for a Software Manual Regression (2024)
Regression testing is a crucial step in the software development process, as it helps ensure that new changes to the system haven't caused any unintended issues. However, conducting a manual regression can be a time-consuming task, especially if you're working with a limited number of resources. In this article, we'll go over how to accurately estimate the time it will take for a software manual regression using a suite of test cases and a limited number of resources.
Step 1: Identify the Total Number of Test Cases
The first step in estimating the time it will take for a software manual regression is to identify the total number of test cases that need to be run. This will give you a clear idea of the scope of the regression and help you plan accordingly.
Once you know the total number of test cases, the next step is to determine the average time it takes for one resource to run one test case. This can be done by timing a sample of test cases and averaging the results. It's important to note that this time may vary depending on the complexity of the test cases.
Step 3: Calculate the Total Time
Once you know the total number of test cases and the average time per test case, you can calculate the total time it will take for all resources to run all test cases. This is done by multiplying the number of test cases by the average time per test case and dividing by the number of resources.
Average time per test case for one resource: 5 minutes
Number of resources: 4
Total time = (1000 * 5 minutes) / 4 resources = 1250 minutes or 20.83 hours
Example 2:
Total number of test cases: 500
Average time per test case for one resource: 10 minutes
Number of resources: 2
Total time = (500 * 10 minutes) / 2 resources = 2500 minutes or 41.67 hours
Example 3:
Total number of test cases: 800
Average time per test case for one resource: 15 minutes
Number of resources: 6
3 of those resources may have other tasks to work on during regression:
Resource 1: Will be working on a project that takes 3 hours per day.
Resource 2: Will be working on a project that takes 2 hours per day.
Resource 3: Will be working on a project that takes 1 hour per day.
Total time per day for the 3 resources = 3 hours + 2 hours + 1 hour = 6 hours
Total time for the regression testing = (800 * 15 minutes) / (6 resources - 6 hours) = 2000 minutes or 33.33 hours
It is important to note that these estimates may fluctuate depending on the progress of the other tasks, and the time it takes to complete these tasks may change, it is a good practice to re-evaluate the progress of the other tasks and adjust the regression testing time accordingly.
It's also important to communicate with the project managers and the team leads to ensure that the resources are available and that their time is used as efficiently as possible. By following these steps, you can accurately estimate the availability of the resources and adjust the total time calculation for the regression testing accordingly.
Expert judgment is a popular technique, relying on the experience and intuition of one or more experts to provide estimates. Work breakdown structure (WBS) is more systematic and detailed, breaking down the testing work into smaller tasks and estimating the effort and duration for each.

How to Calculate Duration of A/B Test? Beyond sample size. From a purely statistical perspective, calculating the expected duration for a test is easy when you have determined the sample size: Expected experiment duration = samples size/number of visitors to the tested page.
Estimate defined per FP is a given value that a test manager defines on the basis of the team experience. It is calculated with respect to time, cost or size (e.g. 10 hours/points, $100/points).
Speeding up regression testing in agile projects can be achieved by automating as much as possible. Automation has many advantages, such as running tests faster, more reliably, and more frequently, detecting defects early, reducing human errors, and increasing test coverage.
If automation tool is not being used for regression testing then the testing process would be time consuming. Regression testing has to be performed for every small change in the code as even a small portion of code can create issues in the software.
Many software development teams have shifted toward Agile paradigms, which prioritize the frequent release and revision of software. Obviously, manual regression testing is a poor fit for this setup. The time required to complete all of the needed tests can be exorbitant, resulting in costly project delays.
Test Estimation is a management activity which approximates how long a Task would take to complete. Estimating effort for the test is one of the major and important tasks in Test Management.
Estimating test efforts is one of the most critical tasks in the software development process. Software Test Estimation (STE) determines or assesses the time and cost needed during the testing process. The following factors are taken into consideration to estimate: Time required for test. Cost Required.
Regression Testing can be manual or automated. If the number of test cases is small, it can be manually managed in less time. However, if the number of regression test cases is significant, automated regression testing is the ideal solution.
