function getTestData() {

    // deriveBits and deriveKey take as input:
    // - derivedKey (actually, a CryptoKey representing a derivedKey)
    // - salt (BufferSource)
    // - hash (which one to use)
    // - iterations (how many times to use it)

    // deriveBits also takes a length. deriveKey uses the length of the output key
    // - length is the number of bits, NOT octets, but it MUST be a multiple of 8
    // - note that result of length(n) is first n bits of length(m) if m>n

    // Variations to test:
    // - empty, short, and fairly long derivedKey
    // - empty, short, and fairly long salt
    // - SHA-1, SHA-256, SHA-384, SHA-512 hash
    // - 1, 1000, and 100000 million iterations

    // Test cases to generate: 3 * 3 * 4 * 3 = 108

    // Error conditions to test:
    // - length null (OperationError)
    // - length not a multiple of 8 (OperationError)
    // - illegal name for hash algorithm (NotSupportedError)
    // - legal algorithm name but not digest one (e.g., AES-CBC) (NotSupportedError)
    // - baseKey usages missing "deriveBits" (InvalidAccessError)
    // - baseKey algorithm does not match HKDF (InvalidAccessError)
    // - 0 iterations
