automated testing – Find out how to validate if .txt file format is right as part of File processing in Automation framework?


In my Selenium+Java automation framework, I must open a .txt file or every other extension file after which see if the textual content is in a selected format. Now, I must see if all strains are on this format and likewise, say in line 2, from substring (7,10) is 2000. Now, is there any methodology in FileUtils API?

I can open the file and assert that it exists. I’m not capable of validate File content material. I would like to do that as part of my Automation undertaking. that is certainly the aim of my undertaking to validate all file format contents.

Like:

0000000TEst  123  234   TEST22 refreence 0002343
00000002000     2343   23343  TEST22000000000000000000
000000003534   3434    34343  3434 343 343 TEst 0000000 000 000              001

Replace in response to solutions:

Thanks! that is very useful, i’ll use this methodology to confirm all of the file codecs with regex.

Additionally, as soon as i validate the format, then i’ll validate some substrings. Now, i’ve the anticipated results of Substring saved in String line2Value = “2000”;

if(line1.substring(7,10).equals(line2Value)){

// syso("That is right....."
}

Now, I've such form of a file during which some part of data, some regex repeats n variety of instances.
{1:TES001}{2:TEST002}{3:
:03:192sscE8wre
:04:TESTLIne
:05C:23434/23423
:06:/
:07:343434,434343//3434343434
:89:?That is take a look at line / EXTRA TEXT LINE
-}
My file can have lots of of those sections, that every one begin from {1:... and finish with -89 }..

how i can test not simply 1 part, however all of those teams are in the identical format :/
