                        Test name (multiple -t options add more tests) e.g -t
                        performance.perf.DiskDrainRate

Resource Files

Ini files represents the ns_server information which is accessible to the tests.

[global] section defines the rest username, password that tests use to login to ns_server.

Example:

[global]
username:Administrator
password:membase

[membase]
rest_username:Administrator
rest_password:asdasd

[servers] section lists port and ssh related information. ssh connection information is required for small subset of tests where test needs to perform installation,backup or restore. If ns_server instances are started using ns_server/cluster_run script then you only need to define ip and port for those nodes.

Example:

[servers]
1:10.1.6.104_1
2:10.1.6.104_2
3:10.1.6.104_3
4:10.1.6.104_4

[10.1.6.104_1]
ip:10.1.6.104
port:9000

[10.1.6.104_2]
ip:10.1.6.104
port:9001

[10.1.6.104_3]
ip:10.1.6.104
port:9002

[10.1.6.104_4]
ip:10.1.6.104
port:9003

Test Execution and Reporting

For every test run testrunner creates a temp folder and dumps the logs and xunit reports in the newly generated folder.

for instance if you run

$ ./testrunner -i resources/jenkins/single-node-centos-32.ini -t setgettests.MembaseBucket.value_100b

you will see this summary after each test is ran:

summary so far suite setgettests.MembaseBucket , pass 1 , fail 0
logs and results are available under tmp-12-11-47

and logs:

$ ls  tmp-12-11-47/
report-12-11-47.xml-setgettests.MembaseBucket.xml   value_100b.log

Development

When using git on Linux/OSX systems, you might run into issues where git incorrectly believes Windows-related files have been modified. In reality, git is merely mis-treating CRLF line endings. Try the following...

$ cd testrunner
$ git config core.autocrlf false

Running End to End Tests Before Submitting a Patch to Gerrit

Testrunner project has different test suites which can be run priori to submitting the code to gerrit. There are test suites that can be run against a single node which validates basic database operations such as persistence and bucket management. There are also key-value clustering related test cases which can be run against Membase/Couchbase 1.8 multiple nodes. Recently we have also been adding more tests which validates basic view functionalities on a cluster and on a single.

"make e2e-kv-single-node"

This make target will start ns_server using cluster_run -n1 and run all the test cases listed in conf/py-all-dev.conf. The test runtime can vary between 15-30 minutes depending on your machine.

Testrunner prints out a human readable pass/fail of the tests. Please refer to the "rerunning test" section for more information of how to re-run one single test against cluster_run.

"make test-views"

This make target will start four ns_server(s) using cluster_run -n4 and runs all the test cases listed in conf/py-view.conf. The test runtime can vary between 30-45 minutes. py-view.conf contains basic test cases which validates clustering operations such as rebalancing.Each test is also parametrized so you can easily modify this run list and change the number of docs or the load_duration.

For instance, test_get_view_during_x_min_load_y_working_set,num-docs=10000,load-time=1,run-view-time=1 test will create a view, inserts 1000 documents, mutate those documents for 1 minute and run view queries in parallel to the load for 1 min. You can easily change the parameters there to insert 1M items and keep the load running for 10 mins for example.

Something went wrong with that request. Please try again.
