How to Create a Test Plan: Template + Best Practices [2026]

A test plan is the document that defines what will be tested, how it will be tested, who will test it, and what constitutes success. Without a test plan, every release is a negotiation between QA and engineering about what is and is not in scope, a negotiation that almost always ends with something important being untested.

A good test plan does not need to be a 50-page enterprise document. For an agile team, it can be a one-page artifact that answers six questions clearly. For an enterprise QA organization, it may be a detailed document covering risk analysis, tool selection, resource allocation, and regulatory compliance requirements.

This guide shows you how to create a test plan for both contexts, and includes a template your team can use immediately.

What is a Test Plan?

A test plan is a formal document that defines the scope, approach, resources, and schedule for testing a software product or a specific release. It answers the fundamental questions of a QA engagement:

•       What are we testing (scope and features)?

•       What are we not testing (exclusions)?

•       How will we test it (approach: manual, automated, exploratory)?

•       Who will test what (team allocation)?

•       When will testing happen (schedule)?

•       What does 'done' look like (exit criteria)?

•       What could go wrong and what is the contingency (risks)?

When Do You Need a Test Plan?

Every release should have some form of test plan, even if it is informal. A formal written test plan is essential when:

•       A new product is entering beta testing or launch for the first time

•       A major release with significant new features or architectural changes is planned

•       Regulatory or compliance requirements mandate documented test planning

•       Multiple QA engineers need to coordinate testing across different features

•       A client or stakeholder needs confidence that a defined QA process was followed

For smaller releases in agile teams, a lightweight test plan embedded in the sprint planning document is sufficient. For major releases, a standalone document reviewed by QA leads, engineering managers, and product managers is appropriate.

Test Plan Template, The 8 Essential Sections

Section 1: Test Plan Identifier and Metadata

Every test plan should have a unique identifier, a version number, an author, a review date, and a linked release or sprint. This metadata makes test plans findable and auditable.

Example: TP-2026-Q2-001 | Version 1.2 | Author: Riya Sharma | Review Date: May 15, 2026 | Release: v3.2 Dashboard Update

Section 2: Introduction and Objectives

Describe the system or release being tested and state the testing objectives clearly. What quality gates must be met before this release can ship?

Example: This test plan covers the quality assurance process for Trulit v3.2, which introduces AI Test Case Generation for API endpoints and a redesigned Test Suite management interface. Testing objectives: verify AI generation accuracy for API test cases, confirm the new test suite UI meets accessibility requirements, validate JIRA defect integration following the API library upgrade.

Section 3: Scope, In Scope and Out of Scope

The scope section is the most important part of the test plan. It defines the explicit boundaries of testing. If something is not listed as in scope, it is understood to be out of scope for this release, which means it may not be tested and the team should be aware of that gap.

In Scope: AI test generation for REST API endpoints, Test Suite UI (Create, Edit, Delete), JIRA webhook integration, mobile responsive layout at 375px and 768px breakpoints.

Out of Scope: Codeless testing module (no changes in this release), G2 review integration (next release), Performance testing (separate engagement).

Section 4: Test Approach and Strategy

Describe how the team will approach testing. This section covers:

•       Test types: functional, regression, exploratory, performance, security, accessibility

•       Execution approach: manual, automated, or a combination

•       Tools to be used: Trulit for test management, Playwright for automated regression, Postman for API testing

•       Environment: staging.trulit.com, seeded with test data set v2.3

•       Data strategy: anonymized production data subset, refreshed before test execution begins

Section 5: Test Team and Responsibilities

Define who is doing what. Ambiguity in responsibilities is the most common cause of untested features.

•       Riya Sharma (QA Lead): Test plan creation, test case review, release sign-off, executive reporting

•       Arjun Mehta (QA Engineer): AI generation feature testing, API test cases, defect management

•       Priya Nair (QA Engineer): UI testing (test suite interface), accessibility, mobile testing

•       Dev Team Liaison: Vinil Pasupuleti, fix verification coordination, environment issues

Section 6: Test Schedule and Milestones

Define when each phase of testing happens relative to the release schedule:

•       May 12 - 14: Test case creation and review complete

•       May 15 - 21: Feature testing on staging environment

•       May 22 - 23: Regression testing (automated Playwright suite + manual critical path)

•       May 24: Defect fix verification and retest

•       May 25: Release sign-off meeting, go/no-go decision

•       May 26: Production deployment

Section 7: Exit Criteria

Exit criteria define what must be true before the release can be approved. These should be specific and measurable:

•       All P0 and P1 defects are Verified Closed

•       Test execution rate is at least 95% of planned test cases

•       Pass rate for regression test suite is at least 92%

•       No open defects with Severity = Critical

•       AI test generation accuracy verified on a representative sample of 50 API test cases (measured by QA lead review)

Section 8: Risk and Mitigation

Identify the testing risks and your plan to mitigate them. Common risks:

•       Risk: Environment instability may delay testing. Mitigation: 24-hour environment availability SLA with Dev team. Backup: local testing environment.

•       Risk: AI generation accuracy below acceptable threshold. Mitigation: Halt AI generation testing, escalate to Vinil, determine if v3.2 AI feature release is postponed to v3.3.

•       Risk: Defect volume exceeds retest capacity before release date. Mitigation: Escalation path defined, QA lead to PM in writing by May 22 if more than 5 P1 defects remain open.

Agile Test Plan vs Traditional Test Plan

Traditional test plans are written once and used throughout a long testing phase. Agile test plans are living documents that are created at sprint planning and updated throughout the sprint.

For agile teams, the test plan structure is the same but the scope is the sprint, not the full product. A sprint test plan might be a single Confluence page or a Trulit test run with a brief planning note attached. The key is that the questions are answered: scope, approach, owner, schedule, exit criteria.
