Artificial Intelligence (AI) is revolutionizing software development, and now with Isolator++ v5, you can harness AI to generate and optimize your C++ unit tests. Whether you’re new to AI-powered testing or looking for advanced techniques, this guide will walk you through how to use AI with the new Isolator++ API.
1. Why Use AI for Unit Testing?
AI can help in the following ways:
- Generate unit tests automatically based on your code structure.
- Improve test coverage by identifying edge cases.
- Optimize existing tests by refactoring or improving assertions.
With Isolator++ v5’s AI-ready API, integrating AI into your testing workflow is seamless.
2. Generating Unit Tests Using AI
To generate a C++ unit test using AI, follow these steps:
- Provide the class you want to test to the AI.
- Use the AI prompt to generate a test following Isolator++ v5’s API.
- Review and refine the generated test.
Example AI Prompt:
You are an expert Typemock developer with deep knowledge of MSTest and Isolator++ v5.
Please open the Isolator++ API summary from www.typemock.com/docs/?book=Ipp&page=llm.htm.
Using the API details described there, generate a C++ unit test for the attached class.
The test should meet these requirements:
- Use MSTest as the testing framework.
- Use Isolator++ v5 for mocking.
- Cover multiple cases for complete code coverage.
- Provide full, compilable C++ code, including necessary headers and using statements.
Make sure to follow Isolator++ v5’s API exactly as summarized in the documentation.
Example of AI-Generated Test Using Isolator++ v5 API:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
#include <Isolator5.h> #include <gtest/gtest.h> using namespace std; class FlightSimulator { public: virtual int GetSpeed() { return 500; } }; TEST(FlightSimulatorTest, TestSpeed) { Isolator a; auto fake = a.Fake.Instance<FlightSimulator>(); a.CallTo(fake->GetSpeed()).WillReturn(1000); ASSERT_EQ(fake->GetSpeed(), 1000); } |
3. Enhancing AI-Generated Tests
AI-generated tests can sometimes miss optimizations. Here are some best practices:
- Refactor redundant code to make tests more readable.
- Ensure realistic mocking for complex dependencies.
- Fine-tune assertions to validate edge cases.
Example of Optimized AI-Generated Test:
|
1 2 3 4 5 6 7 8 9 10 11 |
TEST(FlightSimulatorTest, TestSpeedRefactored) { Isolator a; auto fake = a.Fake.Instance<FlightSimulator>(); a.CallTo(fake->GetSpeed()).WillReturn(1200); ASSERT_EQ(fake->GetSpeed(), 1200); a.CallTo(fake->GetSpeed()).WillReturn(1500); ASSERT_EQ(fake->GetSpeed(), 1500); } |
4. Using AI to Convert Tests from v4 to v5
If you’re migrating from Isolator++ v4 to v5, AI can assist in automating the conversion process.
Example AI Prompt for Conversion:
You are an expert in Typemock Isolator++ v4 and v5.
Convert the following unit test from Isolator++ v4 to v5 syntax, following best practices:
(Provide v4 test code here)
Before (v4 API):
|
1 |
WHEN_CALLED(fake->GetSpeed()).Return(800); |
After (Converted to v5 API):
|
1 |
a.CallTo(fake->GetSpeed()).WillReturn(800); |
