tapir

A command-line tool for managing and executing automated API test cases.

Introduction

tapir is a command-line tool designed to simplify the management and execution of automated API test cases. With tapir, you can easily create, organize, and run tests for your APIs, ensuring they function as expected and meet quality standards.

Why tapir?

Traditional API testing tools like Postman and Insomnia are great, but they often fall short when it comes to:

• Integration with development workflows - They're standalone applications that don't fit naturally into your CI/CD pipeline
• Complete test scenarios - Most tools execute one request at a time, making it cumbersome to test multi-step workflows
• Version control & documentation - Test collections aren't always easy to review, version, or document alongside your code

tapir solves these problems by using Markdown-based test cases that are:

• ✅ Human-readable and self-documenting
• ✅ Easy to version control alongside your code
• ✅ Simple to run from the command line or CI/CD pipelines => it's just a CLI - dotnet global - tool
• ✅ Capable of executing complete multi-step test scenarios

Key Features

• 📝 Markdown Test Cases - Define your API tests in simple, readable Markdown files
• 🔗 Multi-Step Scenarios - Chain multiple API calls together, extract values from responses, and use them in subsequent requests
• 🔍 Smart Validation - Verify status codes, response content, and JSON values using JsonPath expressions
• 💾 Variable Storage - Extract and reuse data between test steps (e.g., retrieve an ID from one endpoint and use it in another)
• 📊 Clear Results - Get detailed test execution reports showing exactly what passed or failed

Quick Example

Here's a glimpse of what a tapir test case looks like:

# TC-Users-001: List all Users - **Date**: 2025-11-05 - **Author**: name-of-author - **Test Priority**: Medium - **Module**: Users - **Type**: Definition - **Status**: Unknown ## Description Tests the Users API by first retrieving all users, verifying the response contains Alice, and extracting her ID for subsequent operations. It then uses Alice's ID to fetch her individual user details and validates the returned data matches expected values (name: Alice, age: 20). This test demonstrates both list and detail API endpoints while showcasing variable extraction and reuse between test steps. ## Preconditions - no pre-conditions ## Steps | Step ID | Description | Test Data | Expected Result | Actual Result | | -------: | ------------------- | ----------------------------------------------------------------- | ---------------------- | ------------- | | 01 | Call users api | Action=Send Method=GET Endpoint=users | Request successful | - | | 02 | Check response code | Action=CheckStatusCode Value=200 | 200 | - | | 03 | Inspect content | Action=VerifyContent File=samples/Users/Definitions/users.json | Should be identical | - | | 04 | Check Alice | Action=CheckContent JsonPath=$[?@.name=="Alice"].name Value=Alice | Content contains Alice | - | | 05 | Retain ID of Alice | Action=StoreVariable JsonPath=$[?@.name=="Alice"].id Name=AliceId | ID of Alice stored | - | | Step ID | Description | Test Data | Expected Result | Actual Result | | -------: | ------------------- | ----------------------------------------------------------------- | ---------------------- | ------------- | | 11 | Get Alice details | Action=Send Method=GET Endpoint=users/@@AliceId@@ | Request successful | - | | 12 | Check response code | Action=CheckStatusCode Value=200 | 200 | - | | 13 | Inspect content | Action=VerifyContent File=samples/Users/Definitions/alice.json | Should be identical | - | | 14 | Check name | Action=CheckContent JsonPath=$.name Value=Alice | Name is Alice | - | | 15 | Check age | Action=CheckContent JsonPath=$.age Value=30 | Age is 30 | - | ## Postcondition - no post-conditions

This test case:

1. Fetches a list of users from the API
2. Verifies the response contains a user named "Alice"
3. Extracts Alice's ID and stores it in a variable
4. Uses that ID to fetch Alice's detailed information
5. Validates the returned data

Run it with: tapir run https://your-api.com -tc TC-Users-001
