Unit Testing and TDD

• Type of tests
• What is a unit test
• Write F.I.R.S.T. tests
• Structure of a unit test
• Given-when-then style
• What is test driven development (TDD)

Installation and Compilation of Google Test

• GTest at GitHub
• Download and building gtest explictly
• Downloading and building automatically using CMake
• Configuration of CLion to run gtest

Writing Test Functions

• Using the gtest test driver
• Writing a TEST() function
• Failing a test
• Expectations vs. assertions
• Relational checks
• Checking strings and native strings
• Checking for thrown exceptions
• Checking floating-point results

Test Fixtures

• Test life-cycle
• Defining a fixture class
• Setup and teardown operations
• Handling fixture data

Parameterized Tests

• Setting up a value-parameterized test
• Parameter value generators
• Setting up type-parameterized test
• Different ways to instantiate parameterized tests
• Type fixtures

Death Tests

• Checking for abnormal program termination
• Death test checks
• Death test predicates
• Checking for non-zero exit code
• Checking for raised signals such as SIGSEGV or SIGFPE

Command-Line Usage

• Running gtest on the command-line or inside a shell script
• Selection a sub-set of the tests to run
• Sample test filters
• Repeated tests
• Disabling selected tests
• Generating XML output for further post-processing

Life-Cycle Methods

• Running code before and after test each test-function
• Running code before and after test each test-group
• Running code before and after test each test-suite

Mock Objects

• How to deal with a dependent object that is not the target for a test
• Using fake objects
• What is a mock object
• Setting up Google Mock (gmock)
• Setting up a test using mock objects

Overview of Other Test Frameworks

• Google Benchmark
• Catch2
• Doctest
• CppUnit
