A LeoFS' continuous integration application

LeoFS Integration Test Tool

Overview

• leofs_test2 is a integration test tool for LeoFS clusters. Tests/Scenarios depend on Erlang and can communicate with the cluster using the distributed Erlang.

Bootstrapping Your Test Environment

Build "leofs_test2"

• "leofs_test2" requires Erlang R16B03-1 or later.
• "leofs_test2" uses the rebar build system. Makefile so that simply running "make" at the top level should work.

$ git clone https://github.com/leo-project/leofs_test2.git
$ cd leofs_test2
$ make

Modify "/etc/hosts" in order to create bucket(s) with "erlcloud"

• Add a domain for the LeoFS bucket in /etc/hosts

$ sudo vi /etc/hosts

## Replace {BUCKET_NAME} with the name of the bucket ##
127.0.0.1 localhost <BUCKET_NAME>.localhost

• Build a LeoFS of your test with "bootstrap.sh" which is included in LeoFS source code

$ cd <leofs-root-dir>/
$ sh bootstrap.sh build integration-test

Starting leofs_test2

• leofs_test2 has options as follows. You can set suitable option(s) with tests.

$ ./leofs_test --help
Usage: leofs_test [-b <bucket>] [-c <cookie>] [-d <leofs_dir>] [-k <keys>] [-m <manager>] [-t <test>] [-h] [-v]

  -b, --bucket   Target a bucket
  -c, --cookie   Distributed-cookie for communication with LeoFS
  -d, --dir      LeoFS directory
  -k, --keys     Total number of keys
  -m, --manager  LeoFS Manager
  -t, --test     Execute a test
  -h, --help     Show the program options
  -v, --version  Show version information

• Default value of options

  • bucket: "backup"
  • cookie: "401321b4"
  • keys: 10000
  • manager: 'manager_0@127.0.0.1'

• Example - Execute the scenarios

$ ./leofs_test -d <leofs-package-dir> -b <bucket> -k 10000 -c leofs_test
