# Description: 

# This script runs security tests for chosen components on a local machine without DABS scripts and ONB. Follow the steps below

# in order to launch tests for a security component:

# 1. Choose a local drive to be used, e.g. p:

# 2. Download a CBR onto the chosen drive.

# 3. Download the security source tree onto the chosen drive, and ensure that your environment variable 

# SECURITYSOURCEDIR points to the relevant root directory.  It helps to use a drive independant value here 

# as this will allow concurrent builds and test runs on seperate drives (assuming the source code has the same path in each case).

# 4. Download ExecTimeOut.exe, which is stored at //PR/share/DABSRelease/buildscripts/, onto the relevant location

# (by default this is the chosen drive's root).  

# 5. Build the security code.  Note that builds require the SECURITYSOURCEDIR environment variable to be set.

# 6. Run or modify the relevant wrapper batch file for your component, which will be stored in the root of the test directory.

# Components Summary

# This script works fine with the following components: Asnpkcs, Caf2, Certman, Common, Crypto, Cryptospi, CryptoTokens,

# FileTokens, Sistools, Streamingcaf, Swi, Switools, Ups. Other components must be tested and therefore 

# further extensions may be needed.
