Richtext Test Cases

0. Insert into bold span

Name	Text
Origin	`Hello World`
Concurrent A	`<b>Hello World</b>`
Concurrent B	`Hello New World`
Expected Result	`<b>Hello New World</b>`

1. Merge Concurrent Styles

Name	Text
Origin	Hello World
Concurrent A	`<b>Hello</b> World`
Concurrent B	`Hel<b>lo World</b>`
Expected Result	`<b>Hello World</b>`

2. Concurrent insert text & remove style

Name	Text
Origin	`<b>Hello World</b>`
Concurrent A	`Hello <b>World</b>`
Concurrent B	`<b>Hello a World</b>`
Expected Result	`Hello a <b>World</b>`

3. Concurrent insert text & style

Name	Text
Origin	`Hello World`
Concurrent A	`Hello <b>World</b>`
Concurrent B	`Hello a World`
Expected Result	`Hello a <b>World</b>`

4. Concurrently insert text and style that expands

This doesn't work well in our implementation

Name	Text
Origin	`Hello World`
Concurrent A	`<b>Hello</b> World`
Concurrent B	`Hello* World`
Expected Result	`<b>Hello*</b> World`

5. Concurrent text edit & style that shrink

Name	Text
Origin	`Hello World`
Concurrent A	`<link>Hello</link> World`
Concurrent B	`Hey World`
Expected Result	`<link>Hey</link> World`

6. Local insertion expand rules

Hello World

When insert a new character after "Hello", the new char should be bold but not link

Hellot World

Name	Text
Origin	`<b><link>Hello</link><b> World`
Expected Result	`<b><link>Hello</link>t<b> World`

7. Concurrent unbold

In Peritext paper 2.3.2

Name	Text
Origin	`<b>The fox jumped</b> over the dog.`
Concurrent A	`The fox jumped over the dog.`
Concurrent B	`<b>The </b>fox<b> jumped</b> over the dog.`
Expected Result	`The fox jumped over the dog.`

8. Bold & Unbold

In Peritext paper 2.3.3

Name	Text
Origin	`<b>The fox jumped</b> over the dog.`
Concurrent A	`<b>The fox</b> jumped over the dog.`
Concurrent B	`<b>The</b> fox jumped over the <b>dog</b>.`
Expected Result	`<b>The</b> fox jumped over the <b>dog</b>.`

9. Overlapped formatting

In Peritext paper 3.2, example 3

Name	Text
Origin	The fox jumped.
Concurrent A	The fox jumped.
Concurrent B	The fox jumped.
Expected Result	The fox jumped.
