Linux support

[cwilliams-ericsson]

This update enables support for Linux by modifying all directory paths to os-independent pathnames, instead of Windows-specific pathnames.

Only pathnames to files have changed. No impact to test files, json files, or test code logic.

This drop should be simple to verify:

• Run a test case (doesn't matter which one). Ensure it doesn't crash. This verifies pathnames to .csv, .json files are correct.
• Run the test case once, answering"no" to specific test log folder, and a second time answering "yes" to specific test log folder. In each case, ensure the logs are written properly to the correct folder.

If both of the above are successful, then the various pathname changes have been verified.

Verify on your Windows platform to ensure no issues. If possible, verify on a Linux platform as well. If you verify on Linux, please let me know.

I have tested with Windows 7, and with Linux Mint v18.1

Also note: pathnames changed slightly in the conf.xml file, so be careful you do not just cut and paste an old conf.xml file into its place without modifying it accordingly.

For example:

"\jsonExpectedFolder\" becomes "jsonExpectedFolder" "\testFiles\" becomes "testFiles" "\certificates\flaskcert1.pem" becomes "certificates/flaskcert1.pem" "\certificates\flaskcbsdiot.key" becomes "certificates/flaskcbsdiot.key" "\certificates\cacertidan1.pem" becomes "certificates/cacertidan1.pem" "\certificates\cpi_ca.crt" becomes "certificates/cpi_ca.crt"
