#1 about 1 min

Introduction to regtest and the ElectrumSV SDK

An overview of testing environments and the tools built around the ElectrumSV SDK.

#2 about 2 min

Pros and cons of public test networks

Comparing the ease of public testnets with their lack of control over block generation and reorganizations.

#3 about 3 min

Why regtest accelerates the software testing process

How local private networks grant control over block mining, reorganizations, and acceptance testing.

#4 about 2 min

Installing and running the ElectrumSV SDK across platforms

Setting up the SDK with unofficial binaries creates a streamlined regtest node on Windows and macOS.

#5 about 3 min

Managing local nodes with the SDK command line

Command-line functionalities manage background nodes and capture deterministic logging outputs for inspection.

#6 about 2 min

Generating blocks and topping up a regtest wallet

Generating enough blocks on a fresh regtest node acquires matured coins for transaction testing.

#7 about 4 min

Running a local Merchant API instance for testing

Launching a local Merchant API handles remote procedure calls and eliminates Docker dependency for end-to-end testing.

#8 about 8 min

Simulating chain reorganizations using custom Python scripts

Utilizing the SDK as a Python library manually forks nodes and alters the block height of a transaction.

#9 about 3 min

Benchmarking code correctness and isolating network latency

Performing controlled benchmarking isolates code correctness from packet loss and network latency issues under high load.

#10 about 2 min

Current limitations of the ElectrumSV SDK tool

System installation dependencies and interactions with closed-source services present ongoing challenges for isolated local testing.

#11 about 4 min

Future roadmap for scalable one-click developer tools

Taking inspiration from other ecosystem tools aims to bundle dependencies into a seamless one-click installation process.
