SQT Security/static testing and dynamic testing


How static testing and dynamic testing differ?

Both static testing and dynamic testing have significance in Software qualification testing (SQT).

What is Static Testing?

In Static Testing, code is checked manually. The main purpose of this testing is quality improvement of software products by finding errors in initial stages of the development cycle. This testing is also known as verification testing or Non-execution technique. Manual or automated reviews of the documents are done during initial phase of testing in Static testing. It inspects work documents and presents review comments. Examples of work documents are Requirement specifications, Source Code, Help or User document, Test Scripts, Test cases etc.

What is Dynamic Testing?

Unlike in Static testing, a code is executed in Dynamic Testing. It checks for functional conduct of software system, CPU/memoryusage and system’s overall performance. This is why it is called dynamic. The main purpose of this testing is to verify that the software product works in conformance with the requirements of business. This testing is also known as validation testing or Execution technique. Black and white box testing are both examples of dynamic testing.

Static Testing Techniques:

  • Technical Reviews: Technical specification of the software product is reviewed by a team consisting of your peers. They try to locate any fault in the specifications and followed standards. This review focuses mainly on the technical documentation allied to the software such as Test plan, Test Strategy and requirement specification documents.
  • Informal Reviews: This is a kind of review which doesn't follow any process to locate errors in the document. Under this method, you just review the document and give informal comments on it.
  • Inspection: The key objective is to find defects and meeting is led by a trained moderator. This is a formal kind of review where strict process is followed to find the defects. To review the work products, reviewers have a checklist.
  • Static code Review: This is a methodical review of the software source code without really executing the code. It checks the coding standards, code optimization, syntax of the code etc. This is called white box testing. At virtually any point during development, this review can be done.

Dynamic Testing Techniques:

·        UnitTesting: Individual units or modules are tested under unit testing.
·        Integration Testing: Developers group individual modules together and test. Objective is to establish what modules are working as anticipated once they are integrated
.
·  SystemTesting: System testing is carried out on the whole system by inspecting whether the system or application meets the prerequisites.

Difference between Static and Dynamic Testing:

Static Testing
Dynamic Testing
Testing is carried out without executing the program
Testing is carried out by executing the program
Static testing performs verification process
Dynamic testing performs validation process
Static testing gives an assessment of code and documentation
Dynamic testing gives bugs/bottlenecks in the software system.
Static testing is about avoidance of defects
Dynamic testing is about discovering and fixing the defects
This testing can be carried out before compilation
Dynamic testing is carried out after compilation
Cost of discovering defects and fixing them is quite low
Cost of locating and fixing defects is comparatively high
Return on investment (ROI) is naturally higher as this process is carried out at an early stage
Return on investment (ROI) is low as this process is carried out  after the development phase

Ccna Training institute in Noida \ skyinfotech

                                                        Difference between CCNA and CCNP Uninitiated offer wonder what is the difference between CCNA and CCNP. Both these certifications are offered by Cisco. CCNA is the intermediate certification offered by Cisco. Below CCNA, Cisco offers CCNT which is a basic entry level certification. But to pass CCNT certification test deep knowledge about networking in needed and honestly speaking CCNT is not truly entry level. But CCNA is definitely more intermediate and knowledge about lot of advanced things about networking is needed to pass CCNA certification test. Lot of research and studying is needed to pass CCNA exam. CCNA is no joke and CCNP is definitely no joke. It is far more advanced than CCNA. One needs to know what are the protocols and know everything about a wan or a lan. CCNP is fa...

Information Security Training And Successfull policy

Seven Characteristics of a Successful Information Security Policy The job of strategy is to arrange core values, shape conduct, give direction to leaders, and fill in as a usage guide. A data security approach is a mandate that characterizes how an association will ensure its data resources and data frameworks, guarantee consistence with legitimate and service prerequisites, and keep up a domain that underpins the core values. The target of a data security strategy and relating program is to: ·         Ensure the association, its workers, its clients, and furthermore merchants and accomplices from mischief coming about because of purposeful or incidental harm, abuse, or revelation of data; ·         Ensure the respectability of the data; and ·         Guarantee the accessibility of data frameworks. Effective data security strategies set up what must be done and why it must be done, however not how ...

SQT Security Importance/Best SQT Training Institute

How important is Software Operational Qualification? Software operational project?qualification (OQ) is considered an obligatory item in validation project of computerized system for any regulated laboratory. Questions like: Is OQ really crucial to a validation project for software like a chromatography data system (CDS)? And how much value addition happens software OQ for commercially available software actually provide to a validation Validationof computerized systems requires that a duly regulated organization functioningunder good manufacturing practice (GMP) or good laboratory practice (GLP) requirements develop or implement a system that generates documented evidence of the work performed and follows a predefined life cycle. The extent of work carried out on each system is dependent on the nature of the software used to automate the process. Using the approach illustrated in the ISPE's Good Automated Manufacturing Practice (GAMP) Guidelines, version 5 ("GAMP 5...
