# Locust Load Test
|
|
|
|
This directory contains scripts to load test cellxgene's backend. It
|
|
primary simulates initial data loading and expression data fetch, which
|
|
are the most common data routes. It currently does not include tests
|
|
for differential expression or re-clustering routes.
|
|
|
|
## Prerequisites
|
|
|
|
You need:
|
|
|
|
- Python 3.6+, and pip
|
|
- cellxgene installed
|
|
- install the locust dependencies in `requirements-locust.txt`
|
|
|
|
## To test
|
|
|
|
1. Choose to run cellxgene in either single dataset or data root mode.
|
|
2. Edit config.py to indicate which datasets to load:
|
|
- in single dataset mode, just set `DataSets=[""]`
|
|
- in dataroot (multi-dataset) mode, add the route names, eg, `DataSets=['foo.cxg', 'bar.cxg']`
|
|
3. Launch cellxgene in the appropriate mode
|
|
4. launch locust, specifying the correct --host argument
|
|
5. point your web browser to the locust http server, usually `http://localhost:8089/`
|
|
|
|
### Single dataset mode
|
|
|
|
- Edit config.py and set `DataSets=[""]`
|
|
- in a shell, run `cellxgene launch somefile.h5ad`
|
|
- launch locust in another shell, `locust --host http://localhost:5005/` (or wherever you are running cellxgene)
|
|
- point a browser to the locust port, usually http://localhost:8089/
|
|
- run test
|
|
|
|
### Multi-dataset mode
|
|
|
|
- Edit config.py and set `DataSets=["datapath1", ...]`
|
|
- in a shell, run `cellxgene launch --dataroot path`
|
|
|
|
The remainder of the steps are same as single dataset.
