Motivation

Improves JSON compatibility for forge test, improve consistency of table rendering

Solution

• Adds JSON compatibility for --summary and --summary + --detailed
• Apply consistent table styling everywhere, improve layout for readability, ensure an empty line before and after the table
• Clarify SummaryReporter to be CoverageSummaryReporter
• Update snapshot reports

lgtm, consistent summaries looks great!

Hey all, previously the table formatting was markdown, and we could pipe it directly into .md files in automated CI actions. However, now the format requires some non-trivial parsing to turn into a MD table (more that what seems feasible with sed and grep). Would it be possible to configure the table formatting to not always use the UTF8_ROUND_CORNERS option from this PR?

Hi @adamegyed

We recently added broad support for JSON serialization of the output rendered to the console using the global --json flag. You are recommended to use this instead. If there are cases where you are running into issues please open a ticket - some are known but it helps us prioritize. What is rendered to the terminal is optimized for human readability.
