what is Benchmark?
A Benchmark is a standard to measure against. If you benchmark an application, all future application changes will be tested and compared against the benchmarked application.
Which of the following Statements about gernerating test cases is false?
1. Test cases may contain multiple valid conditions
2. Test cases may contain multiple invalid conditions
3. Test cases may contain both valid and invalid conditions
4. Test cases may contain more than 1 step.
5. test cases should contain Expected results.
Answer1:
all the conditions mentioned are valid and not a single condition can be stated as false.
Here i think, the condition means the input type or situation (some may call it as valid or invalid, positive or negative)
Also a single test case can contain both the input types and then the final result can be verified (it obviously should not bring the required result, as one of the input condition is invalid, when the test case would be executed), this usually happens while writing secnario based test cases.
For ex. Consider web based registration form, in which input data type for some fields are positive and for some fields it is negative (in a scenario based test case)
Above screen can be tested by generating various scenario's and combinations. The final result can be verified against actual result and the registration should not be carried out sucessfully (as one/some input types are invalid), when this test case is executed.
The writing of test case also depends upon the no. of descriptive fields the tester has in the test case template. So more elaborative is the test case template, more is the ease of writing test cases and generating scenario's. So writing of test cases totally depends on the indepth thinking of the tester and there are no predefined or hard coded norms for writing test case.
This is according to my understanding of testing and test case writing knowledge (as for many applications, i have written many positive and negative conditions in a single test case and verified different scenario's by generating such test cases)
Answer2:
The answer to this question will be 3 Test cases may contain both valid and invalid conditions.
Since there is no restriction for the test case to be of multiple steps or more than one valid or invalid conditions. But A test case whether it is feature ,unit level or end to end test case ,it can not contain both valid and invalid condition in a unit test case.
Because if this will happen then the concept of test case for a result will be dwindled and hence has no meaning.
What is “Quality Assurance”?
“Quality Assurance” measures the quality of processes used to create a quality product.
Software Quality Assurance (‘SQA’ or ‘QA’) is the process of monitoring and improving all activities associated with software development, from requirements gathering, design and reviews to coding, testing and implementation.
It involves the entire software development process - monitoring and improving the process, making sure that any agreed-upon standards and procedures are followed, and ensuring that problems are found and dealt with, at the earliest possible stage. Unlike testing, which is mainly a ‘detection’ process, QA is ‘preventative’ in that it aims to ensure quality in the methods & processes – and therefore reduce the prevalence of errors in the software.
Organisations vary considerably in how they assign responsibility for QA and testing. Sometimes they’re the combined responsibility of one group or individual. Also common are project teams that include a mix of testers and developers who work closely together, with overall QA processes monitored by project managers or quality managers.
Quality Assurance and Software Development
Quality Assurance and development of a product are parallel activities. Complete QA includes reviews of the development methods and standards, reviews of all the documentation (not just for standardisation but for verification and clarity of the contents also). Overall Quality Assurance processes also include code validation.
A note about quality assurance: The role of quality assurance is a superset of testing. Its mission is to help minimise the risk of project failure. QA people aim to understand the causes of project failure (which includes software errors as an aspect) and help the team prevent, detect, and correct the problems. Often test teams are referred to as QA Teams, perhaps acknowledging that testers should consider broader QA issues as well as testing.
Which things to consider to test a mobile application through black box technique?
Answer1:
Not sure how your device/server is to operate, so mold these ideas to fit your app. Some highlights are:
Range testing: Ensure that you can reconnect when leaving and returning back into range.
Port/IP/firewall testing - change ports and ips to ensure that you can connect and disconnect. modify the firewall to shutoff the connection.
Multiple devices - make sure that a user receives his messages with other devices connected to the same ip/port. Your app should have a method to determine which device/user sent the message and only return to it. Should be in the message string sent and received. Unless you have conferencing capabilities within the application.
Cycle the power of the server and watch the mobile unit reconnect automatically.
Mobile unit sends a message and then power off the unit, when powering back on and reconnecting, ensure that the message is returned to the mobile unit.
Answer2:
Not clearly mentioned which area of the mobile application you are testing with. Whether is it simple SMS application or WAP application, you need to specify more details.If you are working with WAP then you can download simulators from net and start testing over it.
What is the general testing process?
The general testing process is the creation of a test strategy (which sometimes includes the creation of test cases), creation of a test plan/design (which usually includes test cases and test procedures) and the execution of tests. Test data are inputs that have been devised to test the system
Test Cases are inputs and outputs specification plus a statement of the function under the test.
Test data can be generated automatically (simulated) or real (live).
The stages in the testing process are as follows:
1. Unit testing: (Code Oriented)
Individual components are tested to ensure that they operate correctly. Each component is tested independently, without other system components.
2. Module testing:
A module is a collection of dependent components such as an object class, an abstract data type or some looser collection of procedures and functions. A module encapsulates related components so it can be tested without other system modules.
3. Sub-system testing: (Integration Testing) (Design Oriented)
This phase involves testing collections of modules, which have been integrated into sub-systems. Sub-systems may be independently designed and implemented. The most common problems, which arise in large software systems, are sub-systems interface mismatches. The sub-system test process should therefore concentrate on the detection of interface errors by rigorously exercising these interfaces.
4. System testing:
The sub-systems are integrated to make up the entire system. The testing process is concerned with finding errors that result from unanticipated interactions between sub-systems and system components. It is also concerned with validating that the system meets its functional and non-functional requirements.
5. Acceptance testing:
This is the final stage in the testing process before the system is accepted for operational use. The system is tested with data supplied by the system client rather than simulated test data. Acceptance testing may reveal errors and omissions in the systems requirements definition( user - oriented) because real data exercises the system in different ways from the test data. Acceptance testing may also reveal requirement problems where the system facilities do not really meet the users needs (functional) or the system performance (non-functional) is unacceptable.
Acceptance testing is sometimes called alpha testing. Bespoke systems are developed for a single client. The alpha testing process continues until the system developer and the client agrees that the delivered system is an acceptable implementation of the system requirements.
When a system is to be marketed as a software product, a testing process called beta testing is often used.
Beta testing involves delivering a system to a number of potential customers who agree to use that system. They report problems to the system developers. This exposes the product to real use and detects errors that may not have been anticipated by the system builders. After this feedback, the system is modified and either released fur further beta testing or for general sale.
What's normal practices of the QA specialists with perspective of software?
These are the normal practices of the QA specialists with perspective of software
[note: these are all QC activities, not QA activities.]
1-Desgin Review Meetings with the System Analyst and If possible should be the part in Requirement gathering
2-Analysing the requirements and the desing and to trace the desing with respect to the requirements
3-Test Planning
4-Test Case Identification using different techniques (With respect to the Web Based Applciation and Desktoip Applications)
5-Test Case Writing (This part is to be assigned to the testing engineers)
6-Test Case Execution (This part is to be assigned to the testing engineers)
7-Bug Reporting (This part is to be assigned to the testing engineers)
8-Bug Review and thier Analysis so that future bus can be removed by desgining some standards
