Introduction to Testing
Software testing is a technique for determining whether the actual software product meets the specified requirements and ensuring that it is defect-free. It is done to examine the quality of software. It entails the use of manual or automated methods to evaluate one or more properties of interest by executing software/system components. In contrast to actual requirements, software testing's goal is to find mistakes, gaps, and missing requirements. Software testing is sometimes referred to as White Box and Black Box Testing. Simply put, software testing is the process of verifying the application under test (AUT).
Static testing is a sort of software testing in which an application is tested without executing any code. In order to discover errors, manual or automated reviews of code, requirement papers, and document design are performed. Static testing's major goal is to improve the quality of software programmes by detecting flaws early in the development process.
Static testing entails manual or automated document evaluations. This evaluation is carried out at the initial round of testing in order to detect defects early in the STLC process. It looks over work documents and gives feedback. Non-execution testing is sometimes known as verification testing.
Examples of work documents are given below −
Help or User document
Web Page content
The following are the primary goals of static testing −
Static testing will help to reduce manufacturing flaws.
Static testing will detect, anticipate, and correct issues as soon as possible.
It is utilised to save time as well as money.
It's used to find faults early in the SDLC process, when they're easier to fix.
Advantages of Static Testing
Product quality has improved. Static testing will improve product quality by identifying faults or problems early in the software development process.
Dynamic testing will become more efficient after static testing. Static testing will boost Dynamic Testing performance since the code will get cleaner and better when Static Testing is completed. Static testing necessitates considerable effort and time in order to build and maintain high-quality test cases.
SDLC costs are lower. Because it identifies defects in the early stages of the software development life cycle, static testing lowered SDLC costs. As a result, changing and repairing the product requires less effort and time.
A code is executed during Dynamic Testing. It examines the software system's functionality, memory/CPU use, and overall system performance. As a result, the term "Dynamic" was coined.
The major goal of this testing is to ensure that the software product meets the needs of the business. This type of testing is also known as execution technique or validation testing.
Dynamic testing runs the software and compares the results to what was predicted. Dynamic testing is conducted at all levels of testing and can be done with either a black or a white box.
The following are some of the benefits of dynamic testing −
It verifies the software application's functionality.
The use of dynamic testing ensures the software product's dependability and consistency.
It can be automated with the use of tools that uncover troublesome and sophisticated defects in the testing process that static analysis cannot cover.
It aids the testing team in identifying the run-time environment's weak points.
The most significant advantage of dynamic testing versus static testing is the greater number of bugs that can be discovered.
Static testing was carried out without the program being executed, whereas dynamic testing was carried out with the program being executed.
Static testing looks for faults in the code, requirement documents, and design documents, whereas dynamic testing looks at the system's functional behavior, memory/CPU consumption, and overall performance of the system.
Static testing focuses on defect prevention, whereas dynamic testing focuses on error detection and correction.
The verification process is carried out by static testing, whereas the validation phase is carried out by dynamic testing.
Before compilation, static testing is conducted, and after compilation, dynamic test is performed.
Structure and statement coverage are static testing approaches, while Boundary Value Analysis and Equivalence Partitioning are dynamic testing techniques.
Difference on the basis of techniques
The following are examples of static testing techniques −
Inspection − The main goal here is to uncover issues. The moderator leads the code walkthroughs. It's a type of formal review in which a checklist is created to go over the work documents.
Walkthrough − A walkthrough is a methodology in which the author leads a meeting to explain the product. Participants will have the opportunity to ask questions, and a scribe will be appointed to take notes.
Technical reviews − A technical round of review is undertaken in this form of static testing to see if the code is written according to technical specifications and standards. The test plans, test strategy, and test scripts are all reviewed in this section.
Informal reviews − Informal reviews are a type of static testing in which the document is reviewed informally and informal feedback is given.
Static code review − This is a method of systematically reviewing software source code without running it. It examines the code's syntax, coding standards, and optimization, among other things. White box testing is another word for this. This review can be carried out at any time during the development process.
Technique of Dynamic testing are given below −
Unit Testing − Individual units or modules are tested by the developers as part of unit testing. It consists source code checking by developers.
Integration Testing − Individual modules are bundled together and tested by developers during integration testing. The goal is to figure out which modules perform as expected after they've been integrated.
System Testing − System Testing examines the entire system to see if it fits the requirements specified in the requirement specification document.
|Static Testing||Dynamic Testing|
|Static testing is a type of white box testing that is performed early in the development life cycle.||Dynamic testing, on the other hand, occurs later in the development process.|
|It is less expensive||It is more expensive|
|Static testing covers more statements in less time than dynamic testing.||There are fewer statement stages in dynamic testing because it just covers a small area of code|
|It is completed prior to the deployment of the code.||It is completed after the deployment of the code.|
|It is carried out at the Verification Stage.||It is carried out at the Validation Stage.|
|This method of testing doesn't involve running any code.||The execution of code is used for this form of execution.|
|Static testing evaluates both the code and the documentation||Dynamic Testing identifies software system bottlenecks.|
|A checklist is generated for the testing procedure in Static Testing Methods||The test cases are conducted using the Dynamic Testing methodology.|
|In Static testing,Walkthroughs and code reviews are types of methods||Functional and nonfunctional testing are both part of dynamic testing.|
To illustrate the difference between static and dynamic testing, following are the examples −
Techniques for Static Testing −
Initially, review the requirement documents and design documents.
Examining the application's graphical user interface
Examining the application's database structure.
Techniques for Dynamic Testing −
Testing the various pages' functionality.
Examining the checkout procedure and available payment options.
Interactions between different pages are being tested.
