TinyTest Standalone Example

This example demonstrates how to use TinyTest in a standalone project using CMake's FetchContent to automatically download and build TinyTest.

What This Example Demonstrates

How to use CMake's FetchContent to automatically download TinyTest
How to create test suites for different types of functions
How to define test cases with expected results
How to execute tests and collect the results

Prerequisites

CMake 3.14 or higher
C++17 compatible compiler
Git (for FetchContent to download TinyTest)

Building and Running

On Linux/macOS

# Make the build script executable
chmod +x build.sh

# Run the build script
./build.sh

On Windows

build.bat

How It Works

CMake is configured to use FetchContent to download TinyTest
The example executable is linked against the TinyTest library
CTest is enabled to run the tests
Several functions are defined and tested:
- add: Adds two integers
- concatenate: Concatenates two strings
- isPrime: Checks if a number is prime
- vectorSum: Calculates the sum of a vector of integers

Code Structure

example.cpp: Contains the functions to test and test suites
CMakeLists.txt: Configures the build system with FetchContent
build.sh/build.bat: Scripts to build and run the example

Understanding the Integration

The key part of the integration is in the CMakeLists.txt file:

# Use FetchContent to download TinyTest
FetchContent_Declare(
  tinytest
  GIT_REPOSITORY https://github.com/headhunter45/TinyTest.git
  GIT_TAG main
)

# Make TinyTest available
FetchContent_MakeAvailable(tinytest)

# Link against the TinyTest library
target_link_libraries(tinytest_example
  PRIVATE
    tinytest_lib
)

This approach automatically downloads, builds, and links against TinyTest without requiring a separate installation step.
