Software Test Estimation: A Step-by-Step Process

What is Software Test Estimation?

Software Test Estimation is a management activity that approximates how long a testing task would take to complete.

The Step-by-Step Estimation Process

Step 1 – Divide the Whole Project Task into Subtasks

• A complex project is divided into modules.
• The modules are divided into sub-modules.
• Each sub-module is further divided into functionality.

In other words, divide the whole project task into the smallest possible tasks.

Step 2 – Allocate Each Task to a Team Member

Assign each task to the appropriate member of the project team.

Step 3 – Effort Estimation for Tasks

Estimate the time and effort required to complete each smallest task.

Consider:

• Task complexity
• Required skills
• Dependencies
• Potential risks

FAQs

1. What is Software Test Estimation?

Software Test Estimation is a management activity that approximates how long a testing task would take to complete.

2. What is the first step in Test Estimation?

The first step is dividing the whole project into:

• Modules
• Sub-modules
• Individual functionalities

In other words, break the work into the smallest possible tasks.

3. Why do we break a project into subtasks for estimation?

Because estimating the smallest tasks and then combining those estimates provides a more accurate approximation than estimating the entire project as a whole.
