# NAME
|
|
# spec.eval - eval a function by name and echo its description field
|
|
#
|
|
# SYNOPSIS
|
|
# spec.eval <function> [OPTIONS...]
|
|
|
|
# OPTIONS
|
|
# <function>
|
|
# Name / glob of one or more functions to evaluate. By default find all
|
|
# functions that match the glob and test each. To run a single function,
|
|
# use the -u --unit option as described below.
|
|
#
|
|
# [-u --unit]
|
|
# Evaluate a single function as indicated by <function>.
|
|
#
|
|
# [-d --depth <depth>]
|
|
# Used to calculate the increment rate of padding added to test blocks.
|
|
# A depth of N will prepend N*2 spaces to test descriptions. No padding
|
|
# is added by default. Use a depth of 0 to NOT output newlines between
|
|
# each test log output.
|
|
#
|
|
# [-s --silent]
|
|
# Do NOT output test descriptions. This option is off by default.
|
|
#
|
|
# DESCRIPTION
|
|
# Run the specified function. Add a -d --description field to tests in
|
|
# order to log a message before evaluating the function. Use the depth
|
|
# option to indicate the indentation factor when logging a message.
|
|
#
|
|
# The process is split up in these steps:
|
|
#
|
|
# 1. Extract test name.
|
|
# 2. Parse description from function definition if available.
|
|
# 3. Parse options
|
|
# + Calculate indentation from --depth * $tab.
|
|
# + Determine newline output.
|
|
# + Skip output if -s --silent is specified.
|
|
#
|
|
# EXAMPLES
|
|
# spec.eval "describe_" --depth 0
|
|
# spec.eval "teardown_"
|
|
# spec.eval "it_"
|
|
# spec.eval "my_test" --unit
|
|
