UniformSharding

import type { UniformSharding } from "https://googleapis.deno.dev/v1/testing:v1.ts";

Uniformly shards test cases given a total number of shards. For instrumentation tests, it will be translated to "-e numShard" and "-e shardIndex" AndroidJUnitRunner arguments. With uniform sharding enabled, specifying either of these sharding arguments via environment_variables is invalid. Based on the sharding mechanism AndroidJUnitRunner uses, there is no guarantee that test cases will be distributed uniformly across all shards.

interface UniformSharding {
numShards?: number;
}

§Properties

§
numShards?: number
[src]

Required. The total number of shards to create. This must always be a positive number that is no greater than the total number of test cases. When you select one or more physical devices, the number of shards must be <= 50. When you select one or more ARM virtual devices, it must be <= 200. When you select only x86 virtual devices, it must be <= 500.
