Test Suite API

testcases . loadTests( tag ) => Array< TestCase >

Load all the given testcases for the tag.

A tag is the string in the above list of test case names not including any extension (e.g. "solidity-hashes")

testcases . TestCase . TEST_NAME

Most testcases have its schema available as a TypeScript type to make testing each property easier.

Deterministic Random Numbers (DRNG)

testcases . randomBytes( seed , lower [ , upper ] ) => Uint8Array

Return at least lower random bytes, up to upper (exclusive) if specified, given seed. If upper is omitted, exactly /lower bytes are returned.

testcases . randomHexString( seed , lower [ , upper ] ) => string< DataHexString >

Identical to randomBytes, except returns the value as a DataHexString instead of a Uint8Array.

testcases . randomNumber( seed , lower , upper ) => number

Returns a random number of at least lower and less than upper given seed.
