You can create and run tests for your agent with the Kapso CLI or with our web app.

​
Kapso CLI

​
Run your tests

When you follow the Run your first agent guide, a test directory with a default test suite is automatically created for you. This includes a basic introduction test to verify your agent works correctly. The default test is located at ./tests/{test_suite_name}/introduction_test.yaml This test checks if your agent can properly introduce itself with the following criteria:
introduction_test.yaml
id: uuid
description: Tests if the agent can properly introduce itself.
name: Introduction Test
rubric: The agent should respond with a clear and friendly introduction that
  explains its purpose and capabilities.
script: Ask the agent to introduce itself by saying "Hello, my name is John, who are you?.".
To run this specific test:
Run Specific Test
kapso test ./tests/{test_suite_name}/introduction_test.yaml
You’ll see detailed test results in your console, including the conversation, feedback, and score:

Introduction Test

Score: 85.00%
Feedback: Evaluation of agent's introduction:

✅ Acknowledged user's name ("Hi John!")
✅ Identified itself as an AI assistant
✅ Expressed willingness to help
✅ Used friendly, welcoming tone
✅ Proactively asked how it could help
⚠️ Gave only a vague description of capabilities ("various tasks") rather than specific examples

Detailed Analysis:
- The agent demonstrated good social etiquette by immediately acknowledging the user's name and responding warmly
- The introduction was clear about being an AI assistant, which establishes appropriate expectations
- The agent showed initiative by following up with "How can I help you today?"
- The main area for improvement would be providing more specific examples of its capabilities instead of the general "various tasks" description
- The response was concise and professional while maintaining a friendly tone

The agent performed well overall but lost some points for not being more specific about its capabilities, which was part of the rubric requirements.

Conversation:

User: Hello, my name is John, who are you?

A: Hi John! I'm an AI assistant here to help you. I can assist you with various tasks and answer your questions.

A: How can I help you today?

You can also run tests with more detailed output using the verbose flag:
Verbose Output
kapso test --verbose

​
Creating additional tests

To create additional tests, you can manually create YAML files in your tests/ directory. Each test suite should have its own subdirectory with a test-suite.yaml file and individual test case files. Test suite structure:
test-suite.yaml
name: Your Test Suite Name
description: Description of what this suite tests
Test case format:
test_case_name.yaml
name: test_case_name
description: What this test validates
script: |
  Instructions for the user simulator
rubric: |
  Criteria for the judge to evaluate
