## Constructors
### RunJudgeContract\(\)
```csharp
protected RunJudgeContract()
```
## Properties

### Judge
The judge under test.
```csharp
protected IRunJudge Judge { get; }
```
#### Property Value

## Methods
### A\_pre\_cancelled\_token\_is\_honored\(\)
```csharp
[Fact]
public Task A_pre_cancelled_token_is_honored()
```
#### Returns
[Task](https://learn.microsoft.com/dotnet/api/system.threading.tasks.task)
### Concurrent\_calls\_start\_together\_and\_complete\(\)
```csharp
[Fact]
public Task Concurrent_calls_start_together_and_complete()
```
#### Returns
[Task](https://learn.microsoft.com/dotnet/api/system.threading.tasks.task)
### CreateContext\(\)
Creates a normal completed-run context.
```csharp
protected virtual RunJudgeContext CreateContext()
```
#### Returns
[RunJudgeContext](/api/tracon.runjudgecontext/)
### CreateJudgeAsync\(\)
Creates the judge under test.
```csharp
protected abstract ValueTask CreateJudgeAsync()
```
#### Returns
[ValueTask](https://learn.microsoft.com/dotnet/api/system.threading.tasks.valuetask\-1)<[IRunJudge](/api/tracon.irunjudge/)\>
### DisposeAsync\(\)
```csharp
public ValueTask DisposeAsync()
```
#### Returns
[ValueTask](https://learn.microsoft.com/dotnet/api/system.threading.tasks.valuetask)
### Every\_score\_in\_a\_judgment\_can\_be\_stored\(\)
```csharp
[Fact]
public Task Every_score_in_a_judgment_can_be_stored()
```
#### Returns
[Task](https://learn.microsoft.com/dotnet/api/system.threading.tasks.task)
### InitializeAsync\(\)
Called immediately after the class has been created, before it is used.
```csharp
public ValueTask InitializeAsync()
```
#### Returns
[ValueTask](https://learn.microsoft.com/dotnet/api/system.threading.tasks.valuetask)
### Name\_is\_a\_stable\_valid\_identifier\_across\_calls\(\)
```csharp
[Fact]
public Task Name_is_a_stable_valid_identifier_across_calls()
```
#### Returns
[Task](https://learn.microsoft.com/dotnet/api/system.threading.tasks.task)
### Repeated\_calls\_with\_the\_same\_context\_complete\(\)
```csharp
[Fact]
public Task Repeated_calls_with_the_same_context_complete()
```
#### Returns
[Task](https://learn.microsoft.com/dotnet/api/system.threading.tasks.task)
### ShouldBeStorable\(RunJudgment\)
Asserts that every score in a judgment satisfies the stored invariants.
```csharp
protected static void ShouldBeStorable(RunJudgment judgment)
```
#### Parameters
`judgment` [RunJudgment](/api/tracon.runjudgment/)
The judgment under test.
#### Remarks
An empty judgment passes: it says the judge reached no decision, and
nothing is written. What must never happen is a judgment that Tracon
then refuses to store — a repeated name, an out-of-range value, a value
shape that does not match its kind, or an over-long version.
### Whitespace\_output\_and\_empty\_tools\_do\_not\_throw\(\)
```csharp
[Fact]
public Task Whitespace_output_and_empty_tools_do_not_throw()
```
#### Returns
[Task](https://learn.microsoft.com/dotnet/api/system.threading.tasks.task)
