disadvantages of automation testing?

Hello , anyone please explain me what is disadvantages of automation testing?

Thanks

Hi Newhere,

Following are some of the disadvantages of automation testing

A. Debugging the test script is major issue. If any error is present in the test script, sometimes it may lead to deadly consequences.
B. Test maintenance is costly in case of playback methods. Even though a minor change occurs in the gui, the test script has to be rerecorded or replaced by a new test script.
C. Maintenance of test data files is difficult, if the test script tests more screens.
D. No human insight
E. Overlooks scripts and style sheets
F. Incapability of dynamic content and multimedia
G. Ignores table linearization and data table association
H. Misleading navigation
I. Conflicting results

Though, there were disadvantages there are lot of advantages also, and use automation tools for the following purposes

a. Reliability
b. Repeatable: you can test how the software reacts under repeated execution of the same operations.
c. Programmable: you can program sophisticated tests that bring out hidden information from the application.
d. Comprehensive: you can build a suite of tests that covers every feature in your application.
e. Reusable: you can reuse tests on different versions of an application, even if the user interface changes.
f. Better quality software: because you can run more tests in less time with fewer resources
g. Fast: automated tools run tests significantly faster than human users.
h. Cost reduction: as the number of resources for regression test are reduced

Thank you sooo mcuh
