If we wanted to use a mock to trigger an exception, what would we use in the blank? # Mock file reader to control its behavior
open = Mock()
def load_file():
Does absolutely nothing other than raise the desired exception
content = open('temp_file.txt') if content.length != 0: return content return None
class TestCase(unittest.TestCase): def test_read_file(self):
Test for IOError
open.______ = IOError

Study Notes
CS 362 Study Notes
-
Requirements Phase
- Craft user stories and use cases to capture the software needs.
- Conduct interviews with stakeholders for insights and specifications.
-
Design Phase
- Develop the architectural layout of the software program.
- Generate a design document to outline the software's structure and elements.
-
Non-Functional Testing Examples
- Scalability Testing evaluates how well a system handles growth.
- Performance Testing assesses speed, responsiveness, and stability under load.
-
Testing Methodology
- Situations like game glitches are best tested manually to observe real-time interactions and anomalies.
-
Importance of Testing
- Ensures safety and compliance in critical applications (Life and Death).
- Enhances customer satisfaction, leading to repeat business.
- Reduces financial expenses through the early detection of issues.
- Saves development time by pinpointing problems before they escalate.
-
Concept of Faults and Failures
- A fault refers to a defect in the code; it is not necessarily a mistake.
- A failure is the observable manifestation of a fault, highlighting its impact on program operations.
-
Error Definition
- An error denotes a deviation from the expected behavior and reflects potential software bugs.
-
Therac-25 Incident
- The technician's rapid input of commands contributed to a tragic error in radiation dosage.
-
Functional Testing Examples
- Regression Testing ensures that new code doesn't adversely affect existing functionalities.
- Unit Testing focuses on testing individual parts of the codebase.
-
Unit Testing Details
- Validates the smallest components for expected outcomes, ensuring code integrity.
- Each unit test must include at least one assertion to verify expected results.
-
Elements of a Testing Framework
- Key components include test runner, test case, test fixture, and test suite for structured testing.
-
Testing Framework Used
- Unittest is the framework adopted in this course for structured testing processes.
-
Test Class Creation
- Create a test class through interactive methods like right-clicking the function/class.
-
Mocks in Testing
- Stubs provide predefined responses; mocks simulate behavior and allow for verification of actions.
- The variable
return_valueis used to set return values in mocks.
-
Testing Output
- The output from mock calls tracks the last function call made, aiding in debugging.
-
Triggering Exceptions with Mocks
- Utilize
side_effectto throw exceptions in testing scenarios to simulate errors.
- Utilize
-
Using Patch
- Patching is necessary to override behaviors of imported modules during tests.
-
Testing Environment Setup
-
setUp()runs before each test, whiletearDownClass()executes after all tests in a class.
-
-
Code Cleanliness in Testing
- Following the DRY (Don't Repeat Yourself) principle minimizes redundancy in setup code.
-
Boundary Testing in Black Box Testing
- Suggested test cases include minimum and maximum valid input scenarios for password validation.
-
Branch and Statement Coverage
- Branch Coverage encompasses Statement Coverage, providing a thorough testing methodology.
-
Input Domain for Functions
- The
my_absfunction operates on real numbers, returning their absolute values.
- The
-
Test Driven Development (TDD) Steps
- TDD emphasizes writing tests before code, exemplified by defining expected outputs first.
-
Continuous Integration Principle
- Every commit to the master branch must undergo building and testing to ensure robustness.
-
Code Review Guidance
- The advice to provide a detour during roadblocks specifically applies to the Code Reviewer role.
-
Role of Acceptance Testing
- Acceptance Testing allows stakeholders to confirm that the software meets their needs and expectations.
