We will learn about what is static testing in software testing, and how is used to examine an application without running any code. We also learn how to do it, why we use static testing, a distinct static testing approach, the benefits of it, and more.
What is static testing in software testing?
Static testing is a type of verification used to test an application without actually implementing its code. Additionally, the technique is economical.
Because it is simpler to locate the causes of faults and rectify them rapidly, It is used in the early stages of development to prevent errors.
In other words, it can be carried out manually or with the aid of tools to enhance the quality of the application by identifying errors at an early stage of development.
While performing this type of testing, we may carry out some of the following significant tasks:
- Review of business requirements
- Design evaluation
- Code demonstrations
- Review of the test documentation
When is Static Testing done?
It is is carried out in the following ways:
- Execute the inspection procedure to thoroughly examine the application’s design.
- For each document being examined, use a checklist to make sure all reviews are completed.
The numerous tasks involved include:
Requirements and Use Cases Validation
It confirms that each end-user activity, together with any accompanying input or output, has been correctly detected. The test cases can be more accurate and complete the more extensive and specific the use cases are.
Functional Requirements Validation
It guarantees that all relevant components are listed in the Functional Requirements. Additionally, it examines the interface listings, hardware, software, and network requirements, as well as database functionality.
The locations of servers, network diagrams, protocol specifications, load balancing, database accessibility, test tools, etc. are all business-level processes.
Prototype/Screen Mockup Validation
Validation of use cases and requirements is part of this phase.
Field Dictionary Validation
Each field in the user interface is sufficiently specified to support test cases for field-level validation. The min/max length, list values, error messages, etc., of fields, are checked.
What are the static testing techniques?
Here are the following techniques used:
- Static Evaluation
- Informal reviews
- Technical/peer review
What is a static testing review?
A review in static testing is a procedure or meeting used to identify any potential flaws in the program’s design. A review’s knowledge of the project’s development for the entire team is another important aspect, and occasionally the variety of ideas may produce fantastic proposals. People immediately inspect the documents, and any inconsistencies are resolved.
Defects of the following kinds are more likely to be discovered:
- Design defects
- Interface standards that are inconsistent
- Incomplete requirements
- Code that can’t be updated
- Variations from the norm
Why static testing in software testing?
The following justifies the use of static testing in software testing:
- To obtain fewer defects at a later testing stage;
- Decreased testing time and expenses;
- In order to increase development productivity;
- Early identification and rectification of defects;
- Shorter development times.
Static testing in software testing: What is Tested?
The following items are evaluated:
- Automation/Performance Test Scripts
- User Manual/Training Guides/Documentation
- Test Plan Strategy Document/Test Cases
- Prototype Specification Document
- Test Data
- DB Fields Dictionary Spreadsheet
- Traceability Matrix Document
- Use Cases
- Unit Test Cases
- System/Functional Requirements
- Business Requirements Document (BRD)
Benefits of using static testing in software testing
Here are some benefits of using static testing:
- Higher-quality products
- Increased effectiveness of dynamic testing
- Lower cost of SDLC
- Quick assessment and feedback
- Bug’s precise position is tracked
In conclusion, static testing is a type of software testing that is performed without executing the code. It includes various techniques such as reviews, inspections, walkthroughs, and code analysis. The primary goal is to identify defects in the early stages of the software development life cycle, which can save time and cost in the long run.
It helps improve software quality by identifying defects in the requirement, design, and code, and ensures that the software meets the required specifications and standards. Overall, this type of testing is an important part of software testing that should be performed in addition to dynamic testing to ensure that high-quality software is delivered.
