Feature: Append content into a UTF-8 ValueStringBuilder

Scenario Outline: Fits in available space
Given a UTF-8 ValueStringBuilder initialized with '<InitializationType>' of length <InitialLength>
And I append '<FirstValue>' to the UTF-8 ValueStringBuilder
And I append '<SecondValue>' to the UTF-8 ValueStringBuilder
When I get the string from the UTF-8 ValueStringBuilder
Then the UTF-8 ValueStringBuilder string should be '<FirstValue><SecondValue>'
Examples:
| InitializationType | InitialLength | FirstValue | SecondValue |
| Span | 11 | Hello | World! |
| Capacity | 11 | Hello | World! |
| Span | 20 | Hello | World! |
| Capacity | 20 | Hello | World! |

Scenario Outline: Grows
Given a UTF-8 ValueStringBuilder initialized with '<InitializationType>' of length <InitialLength>
And I append '<FirstValue>' to the UTF-8 ValueStringBuilder
And I append '<SecondValue>' to the UTF-8 ValueStringBuilder
When I get the string from the UTF-8 ValueStringBuilder via '<GetStringMechanism>'
Then the UTF-8 ValueStringBuilder string should be '<FirstValue><SecondValue>'
Examples:
| InitializationType | InitialLength | FirstValue | SecondValue | GetStringMechanism |
| Span | 11 | Hello, world! | It is mighty fine to see you today. | CreateStringAndDispose |
| Capacity | 11 | Hello, world! | It is mighty fine to see you today. | CreateStringAndDispose |
| Span | 11 | Hello, world! | It is mighty fine to see you today. | RentedBuffer |
| Capacity | 11 | Hello, world! | It is mighty fine to see you today. | RentedBuffer |

Scenario Outline: Append number
Given a UTF-8 ValueStringBuilder initialized with '<InitializationType>' of length <InitialLength>
And I append '<FirstValue>' to the UTF-8 ValueStringBuilder
And I append the Int32 <SecondValue> to the UTF-8 ValueStringBuilder
When I get the string from the UTF-8 ValueStringBuilder
Then the UTF-8 ValueStringBuilder string should be '<FirstValue><SecondValue>'
Examples:
| InitializationType | InitialLength | FirstValue | SecondValue |
| Span | 13 | Hello, world! | 42 |
| Capacity | 13 | Hello, world! | 42 |
| Span | 15 | Hello, world! | 42 |
| Capacity | 15 | Hello, world! | 42 |
| Span | 13 | Hello, world! | -42 |
| Capacity | 13 | Hello, world! | -42 |
| Span | 15 | Hello, world! | -42 |
| Capacity | 15 | Hello, world! | -42 |

Scenario Outline: Append number then string
Given a UTF-8 ValueStringBuilder initialized with '<InitializationType>' of length <InitialLength>
And I append the Int32 <FirstValue> to the UTF-8 ValueStringBuilder
And I append '<SecondValue>' to the UTF-8 ValueStringBuilder
When I get the string from the UTF-8 ValueStringBuilder
Then the UTF-8 ValueStringBuilder string should be '<FirstValue><SecondValue>'
Examples:
| InitializationType | InitialLength | FirstValue | SecondValue |
| Span | 13 | 42 | Hello, world! |
| Capacity | 13 | 42 | Hello, world! |
| Span | 15 | 42 | Hello, world! |
| Capacity | 15 | 42 | Hello, world! |
| Span | 13 | -42 | Hello, world! |
| Capacity | 13 | -42 | Hello, world! |
| Span | 15 | -42 | Hello, world! |
| Capacity | 15 | -42 | Hello, world! |

Feature: Retrieve a Memory from a UTF-8 ValueStringBuilder

Scenario Outline: Retrieve a Memory from a UTF-8 ValueStringBuilder
Given a UTF-8 ValueStringBuilder initialized with '<InitializationType>' of length <InitialLength>
And I append 'Hello' to the UTF-8 ValueStringBuilder
And I append 'World!' to the UTF-8 ValueStringBuilder
When I get the Memory from the UTF-8 ValueStringBuilder
Then the UTF-8 ValueStringBuilder string should be 'HelloWorld!'
Examples:
| InitializationType | InitialLength |
| Span | 10 |
| Capacity | 10 |
| Span | 11 |
| Capacity | 11 |
| Span | 20 |
| Capacity | 20 |

Scenario Outline: Retrieve a Memory with a start position from a UTF-8 ValueStringBuilder
Given a UTF-8 ValueStringBuilder initialized with '<InitializationType>' of length <InitialLength>
And I append 'Hello' to the UTF-8 ValueStringBuilder
And I append 'World!' to the UTF-8 ValueStringBuilder
When I get the Memory starting at <Start> from the UTF-8 ValueStringBuilder
Then the UTF-8 ValueStringBuilder string should be '<ExpectedValue>'
Examples:
| InitializationType | InitialLength | Start | ExpectedValue |
| Span | 10 | 0 | HelloWorld! |
| Capacity | 10 | 0 | HelloWorld! |
| Span | 20 | 0 | HelloWorld! |
| Capacity | 20 | 0 | HelloWorld! |
| Span | 10 | 3 | loWorld! |
| Capacity | 10 | 3 | loWorld! |
| Span | 20 | 3 | loWorld! |
| Capacity | 20 | 3 | loWorld! |

Given a UTF-8 ValueStringBuilder initialized with '<InitializationType>' of length <InitialLength>
And I append 'Hello' to the UTF-8 ValueStringBuilder
And I append 'World!' to the UTF-8 ValueStringBuilder
When I get the Memory starting at <Start> with length <Length> from the UTF-8 ValueStringBuilder
Then the UTF-8 ValueStringBuilder string should be '<ExpectedValue>'
Examples:
| InitializationType | InitialLength | Start | Length | ExpectedValue |
| Span | 10 | 0 | 11 | HelloWorld! |
| Capacity | 10 | 0 | 11 | HelloWorld! |
| Span | 20 | 0 | 11 | HelloWorld! |
