- wrong fix especially now that test encoders work as expected
- touch up `HtmlHelperTest` and `RazorViewTest` since test encoders are now consistent
- remove references to old `Microsoft.Extensions.WebEncoders.Testing` package
This reverts commit a9d5876cd9.
- but leave `FormTagHelperTest` and `ValidationMessageTagHelperTest` cleanup alone
nit: use `string.Empty` in `HtmlHelperLinkGenerationTest`
- prior test encoders were never invoked for `null` or empty `string`s e.g.
``` c#
public static void HtmlEncode(this IHtmlEncoder htmlEncoder, string value, TextWriter output)
{
...
if (!String.IsNullOrEmpty(value))
{
htmlEncoder.HtmlEncode(value, 0, value.Length, output);
}
}
```
- add missing `null` checks and handle `string.Empty` in `TextWriter output, string value, ...` overloads
- better match for the underlying `TextEncoder` behaviour
- `EncoderExtensions` provided an API like `TextEncoder.Encode(TextWriter output, string value)`
- that method calls `Encode(TextWriter output, string value, int startIndex, int characterCount)`
- #3140
- clone `MediaTypeHeaderValue` instance before updating it when content negotiation succeeds
- avoids changes to `MediaTypeConstants` properties and `OutputFormatter.SupportedMediaTypes` entries
- `MediaTypeHeaderValue.Clone()` does not exist in our DNX Core fork of this class
- in previous implementation, was called defensively rather than when required
- update `WebApiCompatShimBasicTest` functional tests to use `MvcTestFixture<TStartup>` everywhere
- #3140 blocked that final migration
- remove `TestHelper` since it's no longer referenced
nits:
- remove comments mentioning `TestHelper`
- correct spelling of "negotiation"
