This request does not change any source code, only tests.
For a change on which I was working, a test passed when run on its own,
but failed when run as part of the full test suite. It turned out that
an existing test had changed a static value,
thousands separator in this case, and failed to restore it.
The test turned out to be AdvancedBinderTest.
The search for the offending test was more difficult than it should have
been because 26 test scripts which had nothing to do with thousands
separator nevertheless changed that value. They all changed
decimal separator, currency code, and compatibility mode as well,
again for no reason. I changed all of those to eliminate those operations.
I changed the following tests, which actually do change the static
properties identified above for a reason, to restore them as part of teardown.
- CalculationTest sets compatibilityMode and locale
- DayTest sets compatibilityMode, returnDateType, and excelCalendar
- CountTest sets compatibilityMode
- FunctionsTest sets compatibilityMode and returnDateType
- AdvancedValueBinderTest sets currencyCode, decimalSeparator, thousandsSeparator
- StringHelperTest sets currencyCode, decimalSeparator, thousandsSeparator
- NumberFormatTest sets currencyCode, decimalSeparator, thousandsSeparator
- HtmlNumberFormatTest sets currencyCode, decimalSeparator, thousandsSeparator
There are a number of situations where HTML write was producing
HTML which could not be validated. These include:
- inconsistent use of backslash terminating META, IMG, and COL tags
- @page style tags in body rather than header. Aside from being
non-standard, HTML Reader treats those as spreadsheet data.
- <div style="page-break-before:always" />, a construct which is
usually better handled through css anyhow.
- no alt tag for images (drawings and charts)
Other problems:
- Windows file names not handled correctly for images
- Memory drawings not handled in extendRowsForChartsAndImages
- No handling of different values for showing gridlines
for screen and print
- Mpdf and Dompdf do not require the use of inline css.
Tcpdf remains a holdout in the use of this inferior approach.
- no need to chunk base64 encoding of embedded images
- support for colors in number format was buggy (html tags
run through htmlspecialchars)
Code has been refactored when practical to reduce the number of
very large functions.
Coverage is now 100% for the entire HTML Writer module,
from 75% lines and 39% methods beforehand.
All functions dealing only with charts
are bypassed for coverage because the version of Jpgraph available in
Composer is not suitable for PHP7. The code will, nevertheless,
run successfully, but with warning messages. I have confirmed that
the code is entirely covered, without warnings, when the current
version of Jpgraph is used in lieu of the one available in Composer.
I will be glad to revisit this when the Jpgraph problem is resolved.
Directory PhpSpreadsheetTests/Writer/Html was created to house
the new tests. It seemed logical to move HtmlCommentsTest to
the new directory from PhpSpreadsheetTests/Functional.
A function to generate all the HTML is useful, especially for testing,
but also in lieu of the multiple other generate* functions. I have
added and documented generateHTMLAll.
The documentation for the generate* functions (a) produces invalid html,
(b) produces html which cannot be handled correctly by HTML reader,
and (c) even if those were correct, does not actually affect
the display of the spreadsheet. The documentation has been replaced
by a valid, and more instructive, example.
The (undocumented) useEmbeddedCss property, and the functions
to test and set it are no longer needed. Rather than breaking
existing code by deleting them, I marked the functions deprecated.
This change borrows a change to LocaleFloatsTest from
pull request 1456, submitted a little over a week before this one.
## Improve NumberFormat Support
First phase of this change included correcting NumberFormat handling
in HTML Writer. Certain complex formats could not be handled without
changes to Style/NumberFormat, and I did not wish to combine those changes.
Once the original change had been pushed, I took this part of it back up.
HTML Writer can now handle conditions in formats like:
[Blue][>=3000.5]$#,##0.00;[Red][<0]$#,##0.00;$#,##0.00
In testing, I discovered several errors and omissions
in handling of some other formats.
These are now corrected, and tests added.
Because even if it doesn't make a difference in practice, it is
technically more correct to call static methods statically. It
also better advertise that those methods can be used from any context.
