PyTest Basics and Setup

7 patterns

Why PyTest is the most popular Python testing framework

PyTest vs unittest vs nose comparison

PyTest installation (pip install pytest)

Project structure for tests

Test file and function naming conventions

Running tests (pytest command)

First PyTest test

Writing Assertions

9 patterns

Why assert is PyTest's core mechanism

Basic assert statement

Assert with messages

Comparing values (equality, inequality)

Checking membership (in, not in)

Checking identity (is, is not)

Asserting exceptions (pytest.raises)

Asserting warnings (pytest.warns)

Approximate comparisons (pytest.approx)

Test Organization

8 patterns

Why organized tests scale with projects

Grouping related tests

Test discovery rules

Conftest.py purpose

Fixtures

9 patterns

Why fixtures provide reusable test setup

@pytest.fixture decorator

Fixture as function argument

Fixture scope (function, class, module, session)

Fixture teardown (yield)

Fixture finalization (request.addfinalizer)

Autouse fixtures

Fixture factories

Conftest fixtures (shared across files)

Parametrize

8 patterns

Why parametrize multiplies test coverage

@pytest.mark.parametrize decorator

Single parameter

Multiple parameters

Parametrize with IDs

Parametrize with indirect fixtures

Combining multiple parametrize decorators

Conditional parametrize

Markers

8 patterns

Why markers categorize and control tests

Built-in markers (skip, skipif, xfail)

@pytest.mark.skip with reason

@pytest.mark.skipif with condition

@pytest.mark.xfail for expected failures

Custom markers

Registering markers in pytest.ini

Running tests by marker (-m)

Part 2: Intermediate6 topics · 47 patterns

Intermediate

Fixture Advanced Patterns

8 patterns

Why advanced fixtures handle complex scenarios

Parametrized fixtures

Fixture request object

Dynamic fixture selection

Fixture dependencies (fixture using fixture)

tmp_path and tmp_path_factory

monkeypatch fixture

capsys for capturing output

Monkeypatch and Mocking

9 patterns

Why mocking isolates code under test

Mock return values and side effects

Mock call assertions

Test Configuration

8 patterns

Why configuration standardizes test behavior

pytest.ini configuration

pyproject.toml configuration

setup.cfg configuration

Command-line options

Addopts for default options

Testpaths configuration

Marker registration

Plugin System

8 patterns

Why plugins extend PyTest capabilities

pytest-cov for coverage

pytest-xdist for parallel execution

pytest-html for HTML reports

pytest-timeout for time limits

pytest-mock for enhanced mocking

pytest-django for Django testing

Installing and managing plugins

Exception and Error Testing

7 patterns

Why error path testing ensures robustness

pytest.raises context manager

Checking exception attributes

Matching exception messages

Testing exception chains

Testing custom exceptions

Testing multiple exceptions

Output and Log Capture

7 patterns

Why capturing output validates behavior

capsys for stdout/stderr

capfd for file descriptors

caplog for log messages

Log level filtering

Asserting log messages

Temporary directory management

Part 3: Advanced6 topics · 45 patterns

Advanced

Test Patterns and Best Practices

8 patterns

Why patterns improve test quality

Arrange-Act-Assert pattern

Parallel Execution

7 patterns

Why parallel tests reduce total time

pytest-xdist installation

Running with -n auto

Worker distribution strategies

Handling shared resources

Fixture scope with parallel tests

Ordering tests for parallel safety

Coverage and Quality

7 patterns

Why coverage measures test completeness

Coverage thresholds

Excluding code from coverage

Coverage in CI pipelines

Advanced Fixture Patterns

8 patterns

Why advanced patterns handle real-world complexity

Factory fixtures

Fixture composition

Lazy fixtures

Context manager fixtures

Async fixtures (pytest-asyncio)

Database rollback fixtures

Shared expensive resource patterns

CI/CD Integration

8 patterns

Why CI integration enables continuous quality

Why Leyaa

Not just a course. A learning intelligence.

Leyaa doesn't just deliver content - it understands where you are, what you need, and how to get you there fastest.

Adaptive Diagnostics

Leyaa identifies which of the 141 patterns you've mastered and which need work - before you waste time on what you already know.

Pattern-Level Precision

Every pattern gets a verdict - Learn, Practice, or Skip - so your study time goes exactly where it counts.

Intelligent Pacing

Leyaa reads your velocity across the whole course and adapts your focus list dynamically, keeping you in the optimal learning zone.

Before & After Visibility

Every assessment creates a snapshot. Retake anytime to see exactly how much you've grown - topic by topic, pattern by pattern.

Learner Autonomy

Leyaa recommends, never restricts. Override any suggestion and explore at your own pace - the system tracks everything regardless.
