The indices are the time in minutes past trade opening time, which was 9: The values are the price in US dollars of one share of Apple stock at that time. And you have to buy before you can sell. What if the price goes down all day?
It is a test to check the code whether it is properly working or not as per the requirement. It is done by the developers Not testers.
This test is basically carried out to check the networking facility, database connectivity and the integration of modules. It is done by the Configuration Team 3 Smoke testing: It is an initial set of test to check whether the major functionalities are working or not and also to check the major breakdowns in the application.
It is the preliminary test carried out by the SQA tester. It is a test to check whether all the modules are combined together or not and working successfully as specified in the requirement document.
When a functionality is added to an application, we need to make sure that the newly added functionality does not break the application. In order to make it sure, we perform a repeated testing which is called Regression Testing.
See the video below for more understanding.
Testing which is based on overall requirements specification and it covers all combined parts of a system. It is also a black box type of testing. In this type of testing the application is tested against heavy load such as complex numerical values, large number of inputs, large number of queries etc.
In this type of testing, the software is handed over to the user in order to find out if the software meets the user expectations and works as it is expected to 12 Black box testing: It is test where a tester performs testing without looking into the code.
OR A testing method where the application under test is viewed as a black box and the internal behavior of the program is completely ignored. Testing occurs based upon the external specifications.
Also known as behavioral testing, since only the external behavior of the program is evaluated and analyzed 13 White box testing: It is a test where a tester looks into the code and performs the testing 14 Alpha testing: In this type of testing, the users are invited at the development center where they use the application and the developers note every particular input or action carried out by the user.
Any type of abnormal behavior of the system is noted and rectified by the developers 15 Beta testing: In this type of testing, the software is distributed as a beta version to the users and users test the application at their sites.
What is Negative Testing? It is the testing of a system or application using negative data is called negative testing, for example, testing password entering 6 characters where it should be 8 characters should display a message When we test an application by putting negative values instead of actual valuesthen the system should not allow the other values rather than the actual value.
The system should give an message that the value is not correct. This is called negative testing. The purpose of negative testing is to detect such situations and prevent applications from crashing.
Also, negative testing helps you improve the quality of your application and find its weak points. Example of Load Testing: A very simple example would be: In the middle of the night, the users are not much to use the ATM machine. Therefore, the load is not much to the machine server.
But when it is day time afternoonit is likely that the there will be many people using the ATM machine. The load to the ATM machine server will be more. Therefore, as a software tester, we should test what is the response time during the heaving use of the machine and light use.Interview Math: Over 50 Problems and Solutions for Quant Case Interview Questions Paperback – January 12, Applying for a job and need to do an SQL interview?
