[SOLVED] Update Test Results to a file using c

hardikgohil1988 · 02-11-2016, 02:02 AM

Hello,

I am trying to write a test application which writes the test results to a file when ever test is performed.

For example the test_report.txt file contents

/********************************************************/
Diagnostic Test Report
/********************************************************/

1.RS232 Test : Not Tested
2.RS232-Front : Not Tested
3.RS232-Back1 : Not Tested
4.RS232-Back2 : Not Tested

The application should update the file as the test is performed and write Tested Ok,Test fail to this file.

And? Where did you stuck? Do you have any problem at all?

Good luck. Maybe you'll go for something like

Code:

FILE *_fbla=NULL;
_fbla=fopen(<path to test_report.txt>,"a");
if(condition_indicating_successful_test){
if(_fbla!=NULL){
fprintf(_fbla,"what a success.\n");
    }//if(_fbla!=NULL){
    }//if(condition_indicating_successful_test){
else{//test failed
if(_fbla!=NULL){
fprintf(_fbla,"test #%&$ seriously.\n");
    }//if(_fbla!=NULL){
}//else{//test failed

Is this a function which is part of a larger program or is it a stand-alone application?

In the latter case, a ">>" command would be just as easy as invoking a program with parameters:
echo "5.RS232-Back3 : Test fail" >> test_report.txt

It is a stand alone application which is used to test the peripherals on-board.

Have you tried to follow the recommendation from marius162?

They are right, you merely need to open a file, write to it, either close it and repeat all, or leave it open and just repeat the writes to the file. There are other means to transit logs around an architecture. What have you tried as far as logs go?

I think you might have mis-interpreted me.

No matter, if you want to add lines to an external file, just use the system() function. (You could also use fopen(), fprintf() if you want to do more work).
