Installation and Uninstall testing is generally accomplished by a software test engineer with the concurrence of a configuration manager (CM). It is also known as Implementation testing and is typically characterized by a testing which comes about while utilizing compile version of codes inside the testing or pre-production environment. This procedure normally takes place beyond the development environment so as to restrict code corruption from future delivery.
Installation testing will check and inspect whether the installed feature are working in a proper manner – including icons, buttons, support documentation, the Readme file, and registry keys. This test also checks that the system creates the right type of directories and correct system files copied in respective directories.
On the other hand, uninstallation testing checks if the system removes the installed directories and files in an appropriate manner. It also ensures that the system removes both configuration and system related files, eventually confirming the recovery of the operating environment to its original state.
Multi-configuration cover is an important part of the test. It may look as if the perfect installation may simply emerge as a plain running of an installation program or the software application. However, the application usually makes use of a set-up program that performs as a multi-configuration cover. This specialized cover ensures installation of the application on an array of operating environments and machines. Installation testing is an important part of testing procedure because every possible arrangement would demand a thorough testing so that users can install and apply the program in a comprehensive manner.
Software development firms have a dedicated department that handles the distribution system. It is responsible for releasing the software to live through goal environments such as an active website. The installation procedure or the software deployment may actually include database schema alterations, in addition to the installation of the fresh software. Under these deployment procedures, you may find instances wherein the so-called back-out process will have an objective that turns over the aimed environment back to the incident where its deployment became ineffective.
You will need to test software’s deployment plan in an area that mocks the live environment. This would eventually result in a rise in the organizational requisites of an exercise like that intends to coordinate the data present in the test deployment environment and the ones that could be found in a live environment with fewer disturbances to the active operation.
For a tester, this phase looks like a dress rehearsal and the dry run, because this sort of implementation testing might probably involve the testing of a process that might occur in the actual installation or perhaps an upgrade of a multiple tear application. A proper and comprehensive set of installation and un-installation tests would ensure a perfect computing environment for the end user.
For an effective install and uninstall test, you will need to cover up possible deficiencies with a foolproof implantation test. This testing is like challenging a full, incomplete or simple upgrade of the install/uninstall procedure. Here are some steps that help you set up solid implementation procedures for conducting an install/uninstall test.
Performance of Implementation
The main characteristic of a test process is to ensure correct performance of the software application. This would assure that the software application would have greater acceptance levels with the clients.
The main function of the testing is to assess and evaluate a software application to make sure that it serves the main purpose for which software developers built it in the first place.
It is also an examination of how it can perform in alignment with the approach, which provides a noticeable and organized method in corroborating the requisites and calculable functioning. There are two classes of testing for software, subsystem and system testing. The first one is the integration testing which uses design as its basis, and the second one is the acceptance testing which uses requirements.
Testing is not just a one-time affair. The type of testing process that you conduct has its fair share of underpinnings that you will need to consider in terms of performing the procedure. The software development process should plan to release a test product so that you can reduce the cost of the probable regression test during the sustenance of the product. Second, the products should first undergo a series of official inspections. After that, each CSCI requisites with every other CSCI will need to track no less than one trial case.
Once that is over, the trial cases mist include white-box tests that have a path-coverage phase that is suitable for the software that is undergoing tests. Trial cases for incorporated tests would need to involve a black box functional, error revival, interface, off limit inputs and stress trials. Then in order for the trial cases to be fully become a completely incorporated system, you would need to perform the tests that are in opposition to the scenarios. These scenarios are series of events created to the model field functions. Integration created by the so-called integration tests would have to be performed by the CM.
The testing professional may have to adhere to some basic rules to be able to maintain a good relationship, not just with the customers, but also with the service buyers. The first important parameter is the testing procedure that functions in harmony with the contract and the RFP. If there would be any reward by form of an additional fee the testing should be motivated accordingly.
On the part of the developer and the buyer, they would need to arrange their contribution for the testing procedure and they would need to record the entire plan along with the trial cases and their comprehensive descriptions. The aforementioned trial cases would have to use the cases grounded on the estimated functional mission scenarios.
Next, the testing procedure would need to involve the load testing for constancy purposes like 96% usage of the CPU the systems constancy expectation. The test proposal would also have to involve an admissible testing stoppage benchmark that establishes the tester’s objectives. When the product passes these set of standards, then it would have the credentials that needs discharged in to in the market.
Moreover, the testing procedures should extensively challenge the interfaces among the in-house and COTS usefulness. The following testing would involve the timing in the middle of the COTS usefulness and the bespoken usefulness. Challenging of the software must involve a noticeable white-box and additional test procedures corroborating the executed software in opposition to what the CM created, such as the requisites traceability matrix and the controlled design records.
A stage of the white-box challenge would need to be quantified which is the one right for the software that is being tried on. Along with the other testing, the white-box would need to make use of a mechanical tool to serve as the means of the software to gauge its testing coverage. To be standardized, all the procedures for challenging the white-box should acquire a code from the library of the CM.
Recurrent builds would necessitate the utility of test automation because more recurrent complies would most likely compel a fast turnaround on every test, particularly in the course of regression challenging. However, that would entail one to have an elevated degree of test grade of test automation. The black box challenging of integration on the other aspect should involve interface, error revival, stress, functional and off limits input challenging. Once the afore-said implementation procedures are over, you can start working on the test in an enhanced manner to ensure software that can work without any serious problems.
Test Implementation Gadgets
Before conducting the test, you may need to pool together important implantation gadgets to ensure proper testing and better results. The goal of testing procedure must include efficient gadgets that can help you conduct proper and result oriented tests. Some of the most useful gadgets that you can find in the market are comparators and memory leak examiners, along with a wide array of other testing gadgets.
You can also use a run-time error determination tool that incorporates an all-inclusive run-time error testing, along with a user-friendly graphical interface. This tool will also assist you in distinguishing the execution mistakes and memory leaks, just anywhere in the software architecture, which are most likely to occur, like the source code system for one.
Another tool is a debugging tool, which is invented to replace a specific system’s realloc or calloc, and some other memory administration practices, while presenting a potent debugging service that could be arrange with run-time.
You can also use relational data editors that would permit you to browse and at the same time edit indirectly, intact subgroups of data from the numerous related tables and you can perform it on a single screen. Extended differencing gadgets are also accessible in the market. Its main function is to serve as an independent product of a complete regression or test work suite of testing gadgets.
The last important gadget is an automated token-by-token comparison utility. It has the ability to accommodate both the text data and the binary data with the predictable discrepancies that will not necessitate for an extensive file description. Moreover, it also evaluates and reports the report files with diverse formats or dates on its header, assesses executables, while paying no attention to the timestamps implanted by the linking procedures.
An additional feature of this modern gadget is that it measures the discrepancy between two files by means of revealing to the user about its matching or where did it encounter differences by means of locating it.
These tools are extremely important for conducting a good test. However, such tools could cost a lot and you may wish to buy the ones that best serve your purpose.
