System Integration Architecture Reviewer

Flashcards generated from system integration architecture, quality assurance, and evaluation lecture notes.

What is System Integration Testing (SIT)?

A QA process performed after separate testing where combined modules are tested as a group to ensure they work together as a whole.

What is System Testing?

The final stage and third level of testing (performed after integration and before acceptance) that provides an end-to-end, black box evaluation against customer requirements for both functional and non-functional aspects.

What is Black Box Testing?

A testing approach focusing on functionality where the tester sees an outside view only and is unaware of inner workings.

What is White Box Testing?

A testing approach where source code and code structure are known, allowing design of test cases based on that knowledge.

What is Gray Box Testing?

A testing approach based on partial code knowledge, where some internal workings are known and some are not.

What is Unit Testing?

Testing applied to the smallest piece of code, such as a function, method, or property.

What is User Acceptance Testing?

A development phase testing conducted in the real world environment.

What is Integration Testing?

Testing a collection of modules and interfaces between components like a building plan for early bug detection, requiring programming knowledge from the integrator.

Why is Integration Testing important?

It checks that modules work together, addresses compatibility and communication issues early, and enhances reliability, performance, and quality.

What is Big-Bang Integration Testing?

The simplest approach where all modules are combined at once; suitable for small systems only and makes errors hard to localize.

What is Bottom-Up Integration Testing?

An integration strategy testing lower levels first and moving upward, using test drivers and testing subsystem interfaces.

What is Top-Down Integration Testing?

An integration strategy testing high-level components first and moving downward, simulating lower modules that are not yet integrated.

What is Mixed Integration Testing?

A sandwiched hybrid approach combining top-down plus bottom-up methods using stubs and drivers to overcome shortcomings.

What are Test Drivers?

Tools or scripts used to drive and pass data to lower-level modules during testing.

What is the purpose of Software Testing?

To ensure the end product meets standards, evaluate functionality, find bugs and defects, and find gaps.

What is Postman?

An API testing tool used to send requests and validate responses for RESTful services, covering functional, load, and security testing.

What is SoapUI?

A tool used for testing web services and APIs (SOAP and REST), SOA, SLAs, message queues, and business logic.

What is Jenkins?

An open-source automation server for CI/CD that builds, tests, and deploys software by auto-triggering frequent test runs on code push.

What is Automation Testing?

Testing executed via software tools running predefined test cases without human intervention.

What is Manual Testing?

Testing conducted by human testers without automation tools.

What is Incremental Testing?

Testing components one at a time, using either top-down or bottom-up strategies.

What is Automated Regression Testing?

Re-running previous test cases after new changes to ensure no new defects are introduced in existing functionality.

What is Architecture Quality Assurance?

Assessing software architecture quality before the coding phase to ensure it is robust, scalable, secure, and maintainable, enabling early error detection.

What is MuleSoft?

An integration platform offering API-led connectivity and reusable assets across on-premises and cloud environments.

What is Apache Camel?

An open-source framework using enterprise integration patterns (EIPs) with a rich library of connectors.

What are Microservices?

Independent, modular services focused on specific functionality that can be deployed separately, interact through APIs, and increase agility.

What is Service-Oriented Architecture (SOA)?

An architecture centered around centralized systems, common messaging protocols, enterprise service buses (ESB), reusability, and standardization.

What is Contract Testing?

Testing that verifies API agreements between independent services.

What is Service Virtualization?

A technique that simulates service interactions during testing.

What is Requirement Traceability?

Linking requirements to functional and non-functional test cases to ensure accountability and track changes.

What is JMeter?

Apache JMeter is a tool used for load and performance testing to analyze data flows across components.

What tools are used for Log Management in integration QA?

ELK Stack and Splunk, which track integration issues in real time.

What tools are used for Monitoring Services?

New Relic and Prometheus, which provide real-time visibility into system health and performance.

What is Software Evaluation?

Running software under known conditions with defined inputs and documented outcomes, then comparing the results to predefined expectations.

What is Verification?

Ensuring the system is built correctly without technical errors, requirements are reviewed, syntactically and logically correct code is written, and the right problem is solved.

What is Validation?

Determining the meaning and content of rules, criteria of adequacy, and overall acceptability of the system.

What are System Requirements?

The foundation of a new system, specifying a condition or capability needed by a user, including environment description, list to fulfill, and verification criteria.

What is Intensional Correctness?

Validating semantic features, domains, keys, and dependencies to avoid data errors and inconsistencies.

What is Normalization in database verification?

Verifying database design, normal forms, table keys, and dependencies to remove redundant data and avoid update anomalies.

What are Update Anomalies?

Issues where performing an update creates inconsistent data or inadvertently removes data.

What is Robustness testing?

Testing rules and control strategies under extreme conditions using the least and most significant input parameters.

What is Accuracy in system evaluation?

Evaluating correct predictions against known data and comparing conclusions with historic data to reflect reality.
