Think about it: we write marketing plans, business growth plans, and even defense plans for sports! We do this to understand the scope of work, set objectives and desired results, allocate required resources, and identify the steps we need to take to reach our goals. Software testing is no exception, and creating a software test plan helps us streamline the process.
Sadly, not everyone believes it’s a good idea to have a plan until it’s time for auditing or product certification. In reality, creating a plan at the start of your process brings a host of benefits, including better QA onboarding and ensuring that your entire QA team understands the required deliverables.
In this article, we’ll explore what a test plan is, why it’s important, how to create a testing plan, and what we use as a sample at Techstack.
Let’s start with the basics.
A test plan is a technical document that contains a detailed description of your test strategy, goals, procedure, resources, schedule, and deliverables. It’s designed by the QA team and used across teams to maintain the transparency, control, and sequence of all testing activity.
A test plan serves many purposes:
To ensure these benefits, an effective and successful test plan has a few key qualities:
Now that we’ve described what a test plan is, let’s look at why it’s important and who will benefit from it.
A test plan benefits mature vendors as it structures and streamlines the testing process. However, it’s equally useful for startups, as bugs and instability can easily hamper your product’s growth. More specifically, developing test plans:
In short, developing and maintaining a test plan benefits every stakeholder, from testers to product owners and developers. So when should you write one?
A product testing plan is usually written during the development stage and is agreed upon by all teams involved (designers, testers, product owners, developers.) This saves time for test execution and lets you address changes that occur during development.
Creating a test plan also comes after you’ve written a test strategy: a document containing general principles of the testing process and how the tests will be run.
Once you have a test plan, there will be cases when you need to revise or rewrite it, such as if you have a high rate of reopened tickets or if detecting and fixing bugs is taking significant time.
You now have a clear picture of when to create or update a test plan.
Now, let’s review creating a test plan for software testing.
There are three basic software testing plans: master, level, and specific. But how to create a test plan in software testing?
This high-level plan overviews the testing process, divided into phases and levels. It describes the testing tactics and strategy, the connections between the different levels and test tasks, the scope of work, and the choices made during the testing process.
These plans cover each level of the testing process, from unit testing to acceptance.
Level test plans contain testing schedules, benchmarks, activities, and templates—details that a master test plan may not specify, along with guidance on how to write a test plan.
There are also test plans for testing and verifying activities that the master test plan may not mention. Usually, they’re created to check how a product performs under specific conditions, and the results of such testing are used for creating risk management strategies.
The most common specific test plans are:
The content of your test plans depends on what needs to be tested. Nevertheless, there are common standards and components you can use as a guide.
Since needs vary by industry, purpose, and product, there’s no one-size-fits-all universal solution for building test plans. However, the IT industry does have standards for creating test documentation. Two common ones are the IEEE 829 and the IEEE 29119.
These standards may be useful if you need quality certification for your testing process. In other situations, you can draw up your own test plan based on the main components it needs to contain.
A test plan should cover all the details regarding the testing process, such as
To cover these things, most test plans contain seven core elements.
This section details the objectives of a specific test project, user scenarios, and limitations. It usually contains three parts:
A clear and accepted scope section will save you unnecessary work and clarify your liability if problems arise.
In this section, you should define the conditions and requirements that must be met to consider the testing successful. These criteria will vary based on the specific development process. For instance, in Scrum, the test plan development may include release quality acceptance criteria and sprint quality acceptance criteria. Furthermore, these criteria will differ from one product to another, so it's essential to describe them as clearly as possible.
Resources cover both human resources—who you’ll need to carry out the testing phase—and technical resources such as materials, environments, software, tools, and hardware. This part, including how to write a test plan for software, may be divided into the following groups:
This section is essential for every test phase, as different test phases require different resources. Knowing them before starting testing will help you meet deadlines and prevent disruption.
This part of your plan describes the output documentation that every QA specialist should provide as a result of their work, such as:
These documents should describe in detail how the assigned task was performed, what was used to complete it, and what the tester achieved.
Your test plan should include a scale of priorities assigned to a bug or error found during testing. These priorities indicate the extent to which a bug affects product performance. How to develop a test plan with defect tracking?
Here’s an example of what a scale could look like:
This is the most important part of any test plan, especially if the tested product is designed for highly-regulated industries. Here, as part of test plan development in software testing, you should document all known risks along with their likelihood, effect on the testing process, and priority, as well as what will be done to prevent these risks from occurring during the testing process.
This section is the base for the product developers and engineers to create a risk management framework. It will also help mitigate consequences as quickly as possible when a problem occurs.
This part is optional, but extremely useful for testing teams. It gives a visual overview of processes and workflows in schemes and algorithms. Here, you can describe the step-by-step execution and decision logic of any testing activity within the project, including how to create a test plan for a project.
Such descriptions help the whole team understand upcoming processes and give a global view of testing activities. Here’s an example:
Your software development test plan may include other sections alongside these common ones, and that’s fine. The aim is to make the plan as detailed as possible and keep it relevant throughout the development and testing cycles. Here’s how you can do it.
Use this 8-step workflow as an inspiration for writing your plan.
After you have completed these tasks, you’ll have a solid basis for your test plan. To flesh out your sections, you can follow the IEEE 829 or IEEE 29119 standard or use our test plan template as a reference.
A test plan is essential for creating an organized, predictable, and easy-to-manage testing process. With a plan in place, you can provide a shared vision of the testing procedure and scope to all stakeholders and external teams. This minimizes misunderstandings and ensures your team is providing value to your product.
Plus, writing a test plan brings structure to your whole process, as it records and streamlines the work of QA team members. Most importantly, it decreases the risk of overlooking problems and bugs affecting your product’s success.
