Introduction to Software Quality Management – Course Assessment

Course Description

This free online course on Introduction to Software Quality Management will begin by introducing you to the evolution of software quality. You will learn about quality assurance, total quality management and process improvement for product quality, reducing costs, as well as accelerating schedules. You will gain an understanding of the ISO 9000 structure and the reasons for acquiring an ISO certification. You will also learn about ISO 9001 requirements.

This course will then introduce you to the Software Engineering Institute Capacity Maturity Model (SEI CMM). You will learn about how the SEI CMM can be used in the capacity evaluation and software process assessment. You will study the key process areas in CMM as well as learn about the Personal Software Process which is a scaled-down version of the industrial software process and is used by individuals. You will also learn about Six Sigma and its aim to eliminate defects.

Lastly, this course will introduce you to software reliability measurement. You will learn about the major problems in software reliability measurements as well as how software reliability keeps changing throughout the life of the product. Furthermore, you will learn about hardware and software failure curves and the differences between them. You will also learn about software reliability estimation technique, Jelinski and Moranda model, as well as Littlewood and Verrall’s model. Start this course today and improve your knowledge of software quality management.

About this Course

After completing this course, you will have an understanding of the fundamental principles and processes of software testing. You will have actively created test cases and run them using an automated testing tool. You will being writing and recognizing good test cases, including input data and expected outcomes.

After completing this course, you will be able to… – Describe the difference between verification and validation. – Explain the goal of testing. – Use appropriate test terminology in communication; specifically: test fixture, logical test case, concrete test case, test script, test oracle, and fault. – Describe the motivations for white and black box testing. – Compare and contrast test-first and test-last development techniques. – Measure test adequacy using statement and branch coverage. – Reason about the causes and acceptability of and poor coverage – Assess the fault-finding effectiveness of a functional test suite using mutation testing. – Critique black-box and white-box testing, describing the benefits and use of each within the greater development effort. – Distinguish among the expected-value (true), heuristic, consistency (as used in A/B regression), and probability test oracles and select the one best-suited to the testing objective. – Craft unit and integration test cases to detect defects within code and automate these tests using JUnit. To achieve this, students will employ test doubles to support their tests, including stubs (for state verification) and mocks (for behavioral verification) (https://martinfowler.com/articles/mocksArentStubs.html). This course is primarily aimed at those learners interested in any of the following roles: Software Engineer, Software Engineer in Test, Test Automation Engineer, DevOps Engineer, Software Developer, Programmer, Computer Enthusiast. We expect that you should have an understanding of the Java programming language (or any similar object-oriented language and the ability to pick up Java syntax quickly) and some knowledge of the Software Development Lifecycle.

WHAT YOU WILL LEARN

• You will gain an understanding of the theory of testing.
• You will practice writing tests for a variety of quality intent, including code coverage, defect finding, and statistical testing.
• You will develop test plans to guide the testing stage of the software development lifecycle.
• You will create defect reports to provide transparency and understanding to supervisors, colleagues, and users.

SKILLS YOU WILL GAIN

• Writing Test Plans
• Writing Defect Reports
• Understanding of Testing Theory
• Writing Tests
• Testing Vocabulary
