This example shows a Ruby error trace from a failed RSpec test run, specifically a `TypeError` about dumping an anonymous class while using YAML serialization with single-table inheritance subclasses in a `before(:all)` hook. The visualization presents the full stack trace, highlighting the chain of method calls from the test assertion through DataMapper’s YAML adapter, Extlib hooks, and RSpec’s example runner. The code uses standard Ruby libraries (`yaml`, `pathname`) and frameworks like DataMapper, Extlib, and RSpec, revealing how the error propagates across the gem’s internal APIs.

This example shows a stack trace from a Ruby on Rails test suite failure, where a YAML parsing error prevents fixture loading. The error message indicates that a `NoMethodError` occurs for `abstract_class?` on `Object:Class` while parsing `galleries.yml` in an ActiveRecord fixture. The visualization presents the nested call stack from RSpec and Rails internals, illustrating the sequence of method calls leading to the failure. It highlights the point where indentation issues in the fixture file trigger the parsing error.

This example captures a runtime error trace from a Ruby on Rails application using DataMapper and SQLite. The visualization maps the call stack of a failed database INSERT operation, showing the sequence of method calls from the SQL adapter through the ORM to the controller and test framework. It highlights the datatype mismatch that occurs when inserting a record into the "locations" table, with the error propagating through the Merb framework and RSpec test suite. The gist documents the exact code path and failure point for debugging.

This example visualizes the error-handling logic in Rails' fixture-loading code by presenting the source of two methods, `parse_yaml_string` and `erb_render`, as a static code excerpt. The visualization shows how a YAML parsing failure is caught and re-raised with a detailed `Fixture::FormatError` message that includes the original error class and message, while also demonstrating the separate ERB rendering step. The display relies on plain text rendering of the Ruby code from `gistfile1.txt`, with no interactive or graphical elements—it simply presents the two method definitions verbatim, highlighting the rescue clause and the embedded string interpolation in the error message.

Gist 207932

This example visualizes a recursive stack overflow error from a Ruby application using DataMapper and Merb. The file displays a long, repetitive backtrace where methods such as `dirty_parents?`, `save_parents`, and `any?` endlessly call each other, causing the system to fail. The visualization likely highlights the looping pattern of the error stack, emphasizing the cycle between the controller and the DataMapper resource internals. It serves as a debugging aid to trace the infinite recursion that leads to the "stack level too deep" exception.

Stack level too deep

This visualization shows a terminal session where a Ruby on Rails test suite fails with a "stack level too deep" SystemStackError, rendering the command output as a plain-text log. The example captures the raw terminal text from a `rake spec:models --trace` run, displaying the rspec test failures and the backtrace pointing to the mongomapper `keys.rb` library. The code uses the standard Ruby runtime and rspec-core, with the output presented literally as the session’s text, reflecting the error’s recursive nature through repeated stack overflow messages. The data source is the command’s stderr and stdout, shown without additional styling or abstraction.

A gist shows a stack trace from a failed Merb application boot, with the error `uninitialized constant CharacterArmor` occurring in `shield.rb`. The rendering visualizes the file paths and method call frames as a hierarchical tree, mapping the sequence of Ruby gem and library calls from `spec_helper.rb` through Merb's bootloader and RSpec runner. The code uses `d3.forceSimulation` for layout and SVG paths to draw connections between frames, with the data sourced directly from the textual trace.

This visualization shows a Ruby error trace from the ANTLR3 parser library, captured as a gist. It displays the sequence of stack frames leading to a `NameError` about an uninitialized constant `Socket::SOL_TCP`, starting from the command-line invocation of `LPCParser.rb`. The rendering relies on the Ruby backtrace formatting and the `antlr3` gem’s debug socket communication, with the output shown as plain text lines. The data source is the literal terminal output from the failed parser run, presented without additional styling or interaction.

Gist 578871

This example shows a Gist titled "Gist 578871" that integrates RSpec mocking and Authlogic into a Cucumber testing environment. It demonstrates how to configure RSpec's mock framework within Cucumber steps by explicitly setting up and tearing down mocks around each scenario. The code loads supporting files like `support.rb`, which requires `cucumber/rspec/doubles` and `rspec/core`, and uses `RSpec::Mocks::setup`, `verify`, and `teardown` in `Before` and `After` hooks. It also activates Authlogic’s test mode and resets `Sham` data. The rendering approach is code-based, not visual, focusing on test configuration.
