Overview

Software Testing at EZEN is oriented towards ‘detection of defects in the software’. Testing is basically concerned with the operation of a system or application under controlled conditions and evaluating the results.

Understanding Business Requirements
(customer requirements)

EZEN’s consulting experience has demonstrated the importance of accurately capturing business and project-specific requirements. Our consultants work closely with you to:

Understand your testing requirements.

Understand the levels of testing to be carried out, existing standards, and test procedures.

Review all technical documentation (requirements specifications, change requests, design documents, installation manuals, user manuals, etc.).

After reviewing and identifying customer requirements and standards, EZEN’s consultants suggest improvements and/or additions to the existing standards. Once they are approved and signed off by the customer, they enter the configuration management process (appropriate version control tools are used). These standards and templates will be enforced by SQA during all levels of testing.

Levels of Testing

EZEN has expertise in testing at all levels. At each test level, the results are documented, reviewed, and signed off. This is done to ensure that quality testing is carried out according to Configuration Management (CM) procedures.

Each level of testing is either considered black box testing or white box testing.

Black box testing: This is not based on any knowledge of internal design or code. The tests are based on requirements and functionality.

White box testing: This testing is based on knowledge of the internal logic of an application’s code. Tests are based on coverage of code statements, branches, paths, and conditions.

Unit Testing

Unit Testing

The level of dynamic testing is first the responsibility of the developers and then of the testers.

Parallel-Audit Testing

Parallel / Audit Testing

In Parallel Testing, the user compares the output of the new system to the output of the current system in order to verify that the new system is operating correctly.

Functional Testing

Functional Testing

This is a category of Black box testing, geared towards the functional requirements of an application and performed by the testing team of the application. Clearly, this is subjective and will depend on the targeted end user or customer.

Usability Testing

Usability Testing

Usability testing is performed to check the 'user-friendliness' of the application. Clearly, this is subjective and will depend on the targeted end user or customer.

Integration Testing

Integration Testing

Upon completion of unit testing, integration testing (basically, white box) commences. The purpose is to ensure distinct components of the application still work in accordance with customer requirements.

System Testing

System Testing

After integration testing, the testing team will begin system testing, which is a type of black box testing. The complete system is configured in a controlled environment to validate its accuracy and completeness in performing the functions as designed.

EndtoEnd Testing

End-to-End Testing

Similar to system testing, end-to-end testing involves testing a complete application in an environment that mimics real-world use, such as interaction with a database, using network communications, or interacting with other hardware, applications, or systems where appropriate.

Regression Testing

Regression Testing

The objective of Regression Testing is to ensure software remains intact. A baseline set of data and scripts will be maintained and executed to verify that the changes introduced during the release have not made any unintended modifications in the code.

Sanity Testing

Sanity Testing

Sanity Testing will be performed whenever cursory testing is sufficient to prove that the application is functioning according to specifications. This level of testing is a subset of Regression Testing.

Performance Testing

Performance Testing

Although performance testing is described as a part of System Testing, it can be regarded as a distinct level of testing. Performance testing will verify the load, volume, and response times as defined by requirements.

Security & Penetration Testing

Security & Penetration Testing

Security Testing verifies how well the system protects itself against unauthorized internal or external access, willful damage, etc.

Recovery-Error Testing

Recovery/Error Testing

This testing is carried out to check how well a system recovers from crashes, hardware failures, or other catastrophic problems.

Compatblity Testing

Compatibility Testing

Compatibility testing is concerned with verifying how well software performs in a particular hardware, software, operating system, network, etc. environment.

Comparision Testing

Comparison Testing

This Testing compares software weaknesses and strengths to competing products.

Comparision Testing copy

Acceptance Testing

Acceptance testing, which is black box testing, provides the client with the opportunity to verify the system's functionality and usability prior to the system being moved to production.
