bbt is a straightforward cross-platform tool designed for black box testing of executable applications via a Command Line Interface (CLI). Standing for Black Box Tester, bbt helps developers efficiently create and execute detailed test scenarios in just a few minutes, employing plain English documentation that aligns closely with Behavior-Driven Development (BDD) practices.

Overview

bbt's unique capability lies in its ability to utilize existing documentation—whether it's acceptance tests, user guides, or README files—as the basis for testing. There is no need for additional scripting or configuration files, streamlining the process significantly. For example, behavior can be expressed in Markdown using the familiar Given/When/Then format:

### Scenario: I want to know gcc version

- When I run `gcc --version`
- Then the output contains `14.2.0`

This simplicity facilitates easy test creation and ensures a direct relationship between the specifications and the actual tests being executed, with no risk of discrepancies arising.

Features

Minimal Syntax Based on Markdown

bbt leverages Markdown to describe scenarios, ensuring that the documentation remains human-readable while also being machine-executable.

• Flexible Headers: Supports Gherkin keywords (# Features, # Scenario, etc.) for scenario identification within the documentation.
• Natural Language Interpretation: The partial parser allows the use of simple English keywords to define steps, making it approachable and easily understood by all team members.

Quick Execution

Executing tests is efficient; simply run:

bbt your_scenario.md

bbt allows running multiple tests in a batch, enhancing workflow and saving time.

Ready-to-Publish Output

Test results are generated in Markdown format, complete with cross-references to the scenario files. This makes sharing and publishing results on platforms like GitHub seamless and straightforward.

Getting Started

Once installed, bbt can generate a template for new scenarios, guiding users effortlessly into their first tests with commands such as:

bbt create_template

This feature underscores bbt's commitment to reducing setup time and complexity.

Why Choose bbt?

• Single Source of Truth: Specifications serve as the only source, minimizing duplicative effort and potential errors.
• Markdown Richness: Leverage existing documentation tools to enhance clarity and context without sacrificing test efficiency.
• Accessible for All: The simplified testing language enables non-coders to participate in scenario creation, fostering greater collaboration within teams.

In summary, bbt is suited for developers looking for an efficient, intuitive black box testing solution that prioritizes simplicity, collaboration, and documentation consistency.
