The current version of Mint is 1.3, dated 1st June 2012.

Overview

Mint is a language and a tool for defining and validating grid or web service test scenarios. Although Mint was designed for use with Cress, it can be used independently of this. As Mint is an extension of Mustard, see the Mustard home page for the context of Mint. See the Cress home page for an overview of Cress.

Mint has been used to validate services in the following domains:

Mint validates implementations using:

Tools

Mint creates and runs tests expressed using the Mustard scenario notation. It relies on the cress_common.pm Perl module borrowed from Cress.

Installation

To run Mint requires Perl 5 or similar and the Sun Java Development Kit 1.5 or later. Mint has been run on Windows (XP and 7, under CygWin), but should also run on various versions of Unix.

A Unix-like installation is assumed in the following, though it should be possible to install and run on other platforms where Perl and Java run. It is assumed that the files are extracted to $HOME/bin/mint.

In a few places in the code, a Unix-like environment is assumed. For example, Macintosh end-of-line may not be correctly handled. Paths and filenames are assumed to have '/' separators. Search paths are assumed to have ':' separators. On a Windows system, it is suggested that CygWin be used; ActivePerl may be suitable but has not been tried.

The following environment variables should be set up (e.g. in your .profile, .cshrc or Windows XP environment variables):

Variable Meaning
JAVA_HOME (used by java and javac) JDK installation directory
PATH (used by command-line) a directory path used by a shell to locate executables, e.g. to include $HOME/bin/mint/bin
PERLLIB (used by Perl) a directory path used by Perl to locate modules (cress_*.pm), e.g. $HOME/bin/cress/bin.

Mint

This script takes a filename on the command line. "file[.mustard]" should contain a Mustard test file. The main file can optionally be followed by feature or service names to restrict testing to these. A partner "feature" has the form <service>.<partner>.

Using a ws vocabulary option is usually preferable as gs invokes the Globus version of WSDL2Java. The latter sometimes does not translate WSDL correctly as it is based on an older version of Axis.

Note that Mint relies on an environment (test files) having been set up by Mustard, so it may not be sensible to run Mint directly. Also note that testing a partner on its own will not work if it relies on faults defined only by the partner service.

Command-line options are:

Option Meaning
-e level use the given error reporting level (3 - panics, 2 - these plus errors, 1 (default) - these plus notes, 0 - these plus diagnostics)
-h help on parameters
-j suppress WSDL translation to Java (translated by default)
-k key key for server authorisation (user:password@host) used as the default for 'target.url' in a service properties file; if the host is given, it replaces the one in this file
-p mode[runs] performance mode (c concurrent, s sequential), optionally followed by the number of runs (default 20)
-r directory root directory for main service (default current directory)
-t properties a comma-separated list of target properties in the format partner[@file[.properties]]
-v vocabulary use the named vocabulary (gs, ws - always used for main service file)
service [partner...] service and optional partners (test all by default)
