Test Tools and their purposes
Requirement management tools
Store requirements, check for consistency, allow requirements to be prioritized, trace changes, coverage of requirements etc.
Incident management tools
Store and manage incident reports, facilitating prioritization, assessment of actions to people and attribution of status etc.
Configuration management tools
Store information about versions and builds of software and testware; enable traceability between testware and software work products etc. 
Review tools
Store information, store and communicate review comments etc.
Static analysis tools (D)
The enforcement of coding standards, the analysis of structures and dependencies, aiding in understanding the code etc.
Modeling tools (D)
Validate models of the software, find defects in data model, state model or an object model etc.
Test design tools
Generate test inputs or executable tests, generate expected out comes etc.
Test data preparation tools
Preparing test data, Manipulate databases, files or data transmissions to set up test data etc.
Test execution tools
Record tests, Automated test execution, use inputs and expected outcomes, compare results with expected outcomes, repeat tests, dynamic comparison, manipulate the tests using scripting language etc.
Test harness/unit test framework tools (D)
Test components or part of a system by simulating the environment, provide an execution framework in middleware etc.
Test comparators
Determine differences between files, databases or test results post-execution comparison, may use test oracle if it is automated etc.
Coverage measurement tools (D)
Measure the percentage of specific types of code structure (ex: statements, branches or decisions, and module or function calls)
Security tools
Check for computer viruses and denial of service attacks, search for specific vulnerabilities of the system etc.
Dynamic analysis tools (D)
Detect memory leaks, identify time dependencies and identify pointer arithmetic errors.
Performance/Load/Stress Testing tools
Measure load or stress, Monitor and report on how a system behaves a variety of simulated usage conditions, simulate a load on an application/a database/or a system environment, repetitive execution of tests etc.
Monitoring tools
Continuously analyze, verify and report on specific system resources; store information about the version and build of the software and testware, and enable traceability.
Tool support using other tools
Some tools use other tools (Ex: QTP uses excel sheet and SQL tools)
Potential benefits and risks of tool support for testing
  • Repetitive work is reduced
  • Greater consistency and repeatability
  • Objective assessment
  • Ease of access to information about tests or testing
  • Unrealistic expectations for the tool
  • Underestimating the time and effort needed to achieve significant and continues benefits from the tool
  • Underestimating the effort required to maintain the test assets generated by the tool
  • Over-reliance on the tool
Special considerations for some types of tools
Following tools have special considerations         
ü       Test execution tools
ü       Performance testing tools
ü       Static testing tools
ü       Test management tools
                            Introducing a tool into an organization               
The following factors are important in selecting a tool:
  • Assessment of the organization maturity
  • Identification of the areas within the organization where tool support will help to improve testing process
  • Evaluation of tools against clear requirements and objective criteria
  • Proof-of-concept to see whether the product works as desired and meets the requirements and objectives defined for it
  • Evaluation of the vendor (training, support and other commercial aspects) or open-source network of support
  • Identifying and planning internal implementation (including coaching and mentoring for those new to the use of the tool)
The objectives for a pilot project for a new tool
  • To learn more about the tool
  • To see how the tool would fit with existing processes or documentation
  • To decide on standard ways of using the tool that will work for all potential users
  • To evaluate the pilot project agonist its objectives
Successes factors for the deployment of the new tool within an organization
  • Rolling out the tool to the rest of the organization incrementally
  • Adapting and improving process to fit with the use of the tool
  • Providing training and coaching/mentoring for new users.
  • Defining usage guidelines
  • Implementing a way to learn lessons from tool use.
  • Monitoring tool use and benefits.
