For any venture to succeed, proper implementation and assessment estimation are as crucial as the developmental cycle. Adherence to the estimated projection is key in maintaining a good rapport with the client.
Experience plays a pivotal role in estimating the “Software Testing Efforts”. Engaging in various projects enables us to create an accurate estimation for the testing cycle.

It is clear that one cannot blindly assign a number of days for any testing task. The estimate for testing should be accurate and realistic.
This guide will provide some crucial guidelines that will be very helpful in forming an accurate testing estimate in a rather straightforward manner.
Here’s What You’ll Learn:
Process of Test Estimation
“Estimation is a process through which an estimate or approximation is gleaned, which is a usable value even when input data might be incomplete, uncertain, or unstable.” [Citation: Wikipedia]
As professionals, we encounter a range of responsibilities, tasks, and deadlines. There are two strategies to solve a problem.
The first strategy is a reactive approach where we find a solution to the problem only after it surfaces.
In the alternate method, also known as a Proactive Approach, we prepare ourselves well in advance before the problem arises, leveraging our past experiences to resolve the issue when it comes to light.
Estimating, therefore, can be considered as a strategy employed when we prefer being proactive about a problem.
Thus, Estimation can be used to predict the time and cost effort needed to complete a specific task. When the testing team can estimate the problem at hand, it becomes easier for them to provide an optimum solution.
The concept of estimation could then be more formally defined as a rough calculation of the anticipated cost of a task.

Basic Requirements
Below are the Basic Requirements for the Process of Test Estimation.
#1) Learnings from previous experiences: It can be beneficial to use some time to recall past projects that brought similar challenges to the present project.
#2) Available documents or artifacts: The test management repository tools may prove useful in these circumstances as they store the necessary documents explaining the requirements. The testing team can refer to these documents to clearly define the scope of the project.
#3) Assumptions about the type of work: Past experience can assist us in making assumptions about the project. This is where having experienced professionals on the team becomes crucial. Testing managers can draw from their knowledge to deliver the desired outcomes.
#4) Identifying Potential risks and Threats: The testing team should also try to foresee any potential risks, challenges, or pitfalls that might be faced by the team in the future.
#5) Assessing whether the documents have been baselined: The testing team also has to assess whether the requirements have been finalized or not. If the documents have not been finalized, it is important to understand the frequency of changes.
#6) Clarifying all tasks and dependencies: The team should clearly designate roles and responsibilities to all individuals who will be conducting the estimation process.
#7) Documenting and tracking the estimation data: All relevant information pertaining to the estimation process should be recorded.
#8) Activities to be done during the test estimation process:
- Form a team to conduct estimations.
- Break the project down into project phases and subsequent activities.
- Calculate the estimation based on previous projects and professional experience.
- Identify potential threats and develop strategies to counter these risks.
- Review and document pertinent aspects of the work.
- Submit the work to the relevant stakeholders.
Key Test Estimation Techniques
Some essential techniques for test estimation include:
- Test point estimation
- Work-phase based estimation
- Use case point estimation
How and where to implement these methods:
#1) Test Point estimation is a straightforward and easily understood estimation technique that is widely used in software testing. This technique’s iterative phases and simplicity are its primary features.
#2) Work-phase based estimation is used to make an initial rough estimate of a particular phase (usually the shortest and simplest phase), after which the testing team gradually adds other phases to the initial estimation to form an appropriate overall estimate.
#3) The Use-Case Point estimation method estimates based on the use cases where Unadjusted Actor Weights and Unadjusted Use Case Weights are used to determine software testing estimates.
Insights on Test Point Estimation Technique
The following steps are carried out when utilizing the test point estimation technique:
(Consider the following weights which may differ from project to project – some are weights for the programming language based on the code’s complexity, application weight based on the type of application, and test weights which are assigned based on the various stages of software testing.)
Unadjusted Test Points are multiplied by CWF to obtain the test sizing in Test Point’s Size.
The Productivity Factor represents the time required for a test engineer to complete testing one Test Point.
The testing effort in person-hours is calculated by multiplying the Test Point size by the Productivity Factor.
The following variables are considered in computing the test point estimation technique:
- Test requirement complexity
- Interface with other requirements
- Total number of verification points
- Test data baseline
We then need to assign weight vectors for each data variable and arrange them as follows:
