How does CEA testing prove valuable in detecting recurring cancer?

A rising CEA level may be the first sign of cancer return, and may show up months before other studies or patient symptoms would raise concern.


What is system testing in manual testing?

System testing is the type of testing to check the behavior of a complete and fully integrated software product based on the software requirements specification (SRS) document. Its a series of different tests whose sole purpose is to exercise the full computer based system. In SDLC, System Testing is perform as the first level of testing where the system is tested as a whole. In System Testing, we test the both Functional as well as Non Functional parameters of Software Testing. System testing involves testing of following: Testing the fully integrated applications including external peripherals in order to check how components interact with one another and with the system as a whole. This is also called End to End testing scenario. Verify thorough testing of every input in the application to check for desired outputs. Testing of the user's experience with the application. . That is a very basic description of what is involved in system testing. You need to build detailed test cases and test suites that test each aspect of the application as seen from the outside without looking at the actual source code. Every software testing company consider all these things while performing system testing.


How software testing differ from program testing?

Software testing and program testing differ in scope and purpose. Program testing focuses on individual components or modules of a program, ensuring they function correctly in isolation. It is narrower in scope and often involves unit testing. Software testing, on the other hand, is broader, encompassing the entire system, including integration, functionality, performance, and security, to ensure the software meets user requirements and works seamlessly. For a comprehensive understanding of these concepts, enrolling in Uncodemy's top-notch software testing courses equips learners with practical knowledge and skills to excel in both program and software testing, addressing industry demands effectively.


What is the difference between block box and white box testing?

White box testing or unit testing: To do white box testing, knowledge of internal logic code is required. It is mostly done by developers.Black box testing: The functionality of an application is tested; logic code is not required. This testing is done by testers.Block box or system testing: Testing the application without knowledge of underline code of the application. it is done by the testers.
