    Bug 797158 - gnc:make-account-sel-limited-option is not working
    
    Option was being deliberately reset to default_value every time.

    [test-stress-options] improve coverage
    
    * improve documentation
    * reuse (create-test-data) for various regular transactions
    * run (create-test-invoice-data) for business invoices
    * fix max arguments which would crash for reports without options
    * if report has start-date and end-date, insert valid dates to ensure
    report runs on non-null book data.
    * enable testing of previously disabled reports
    * also dump book and invoices generated in populated book
    * modify output to show full backtrace on error: In case of test
    failure, previous would show a shortened exception name. Change to
    display full backtrace, similar to crashing in live code. Uses
    gnc:apply-with-error-handling existing API call.
    
    Also clean up code.

-;; NOTE
-;; ----
-;; SIMPLE stress tests by default
+;; NOTE: This file will attempt to run most reports and set their
+;; options. First, the reports are run on empty-book, then on a book
+;; with sample transactions and invoices.
+
+;; SIMPLE stress tests by default will run tests as many times as the
+;; maximum number of multichoice. if the option with most choices is a
+;; price-source with the 4 possibilities, average-cost,
+;; weighted-average, pricedb-nearest, pricedb-latest;
+;; simple-stress-test will run it 4 times using each price-source. Other
+;; options with fewer options are cycled e.g. multichoice 'simple
+;; 'detailed will be run with 'simple 'detailed 'simple 'detailed
+;; while the price-source gets more exhaustively tested. The report is
+;; only run to verify it does not crash. No testing of report output
+;; is actually done.
 ;;
-;; PAIRWISE COMBINATORICS are enabled by setting environment variable COMBINATORICS
-;; to the fullpath for the compiled jenny from http://burtleburtle.net/bob/math/jenny.html
+;; PAIRWISE testing will improve test coverage. From the above
+;; example, if the stress test runs: average-cost + simple,
+;; weighted-average + detailed, pricedb-nearest + simple,
+;; pricedb-latest + detailed. No testing of average-cost + detailed is
+;; performed. PAIRWISE testing ensures pairs are tested adequately and
+;; uses an external tool jenny to generate combinations. The full-path
+;; to jenny must be specified in the COMBINATORICS environment
+;; variable. The n-tuple may be modified -- see the global variable
+;; N-TUPLE. The jenny.c is copied in the "borrowed" folder in GnuCash

    this function creates some business data. moved from test-invoice.scm
    without the invoice-specific tests. verified all invoices/bills are

    it returns a vector-list of the 8 invoices generated.

    Bug 797319 - Mauritanian ouguiya MRO shows too few decimals
    
    Changed MRO smallest-fraction to 100 based on information provided
    by the reporter. ISO4217 has moved the MRO to the "Historical Currencies"
    list that doesn't include CcyMnrUnits.
