| ## NodeResourceTopologyMatch Tests | ||
|
|
||
| The NodeResourceTopologyMatch plugins involves with different Topology Manager configurations. | ||
|
|
||
| This differences leads to changing in the plugins behavior and needs to be tested in comprehensive way. | ||
|
|
||
| The most complicated and common case for these plugins is when ```TopologyManagerPolicy=single-numa-node``` and ```TopologyMangerPolicy=container```. | ||
|
|
||
| Since this specific configuration has so many edge cases and permutations, we decided to summarize all of them in a table below. | ||
| This will help us track the coverage and made sure the plugins are fully tested. | ||
|
|
||
| ### Table guidelines: | ||
| - All pods are ```Guaranteed``` QoS pods, IOW all containers are asking for an equal ```request``` and ```limit``` values. | ||
| - The table describes the coverage of the ```TopologyManagerPolicy=single-numa-node``` and ```TopologyMangerPolicy=container``` configuration. ```TopologyMangerScope=pod``` is basically the same case as ```TopologyMangerPolicy=container``` but with a single container. | ||
|
|
||
| #### <a>Test types</a>: | ||
| - Each test type can be tested with various resources types. For example a test that check for overallocation, can be tested with CPUs overallocation or Memory overallocation or both. | ||
|
|
||
| #### Table legend: | ||
| - R = Requested resources by the container | ||
| - NUMA = Resources available under a NUMA. | ||
| - R [<,=,>] NUMA = The requested resources by the container is (less/equal/more) than the resources available under the NUMA. | ||
| - R [<,=,>] Node = The requested resources by the container is (less/equal/more) than the resources available under the Node. | ||
| - SUM(R) = accumulate the resources of all containers | ||
| - Node = Resources available under the whole node. | ||
| - N = Any number of containers | ||
| - NVM = What ever value in the field, it won't affect the test result (a placeholder for any possible value). | ||
