Study Notes

Static Testing

Finds defects early in the development process, reducing the cost and difficulty of fixing them later.
Improves software quality by preventing defects from being introduced.
Complements dynamic testing, which involves executing the software and checking results against expected outcomes.

Dynamic Testing

Finds defects that static testing may miss, such as performance, usability, or integration issues.
Not sufficient on its own to ensure quality, as it may not cover all possible scenarios, inputs, or paths.

Testing Metrics

The chart represents metrics related to testing of a completed project.
X-axis represents Time.
Y-axis represents Count.
Line A represents the Number of open bugs.
Line B represents the Total number of executed tests.

Continuous Integration

A practice that supports shift-left in testing, involving frequent integration and testing of software components.
Reduces the time between the introduction of a defect and its detection, reducing the cost to fix it and the risk of accumulating defects.

Decision Table

Defines the upgrade eligibility for a room upgrade system.
A Preferred Guest Card holder with a Silver room is eligible for an upgrade to Gold Luxury.
A non-Preferred Guest Card holder, regardless of room type, is not eligible for an upgrade.

Configuration Management

Helps ensure that all relevant project documentation and software items are uniquely identified in all their versions.
Supports testing by providing traceability, consistency, and control over the test artifacts and the software under test.

Use Cases

Suitable for testing applications that involve a high level of interaction between the user and the system, such as a new navigation system.
Helps to specify the functional requirements of the system, such as entering a destination, selecting a route, and following directions.

Cost as an Exit Criterion

Cost can be regarded as an exit criterion for testing, as it affects the profitability and feasibility of the software product.
Helps to avoid spending too much money on testing, which may result in an unprofitable product.
Should not be the only exit criterion, as it may not reflect the true quality and risk level of the software product.

Test Pyramid

The tests at the bottom layer of the pyramid run faster than the tests at the top layer.
The tests at the bottom layer are more focused, isolated, and atomic, testing individual units or components of the software system.
