I am trying to implement an Assert over my function which is called in separate project. The function called is as follows:
public async Task<List<DynamicTableEntity>> PopulateTable(
string documentId,
IEnumerable<string> lines,
JsonSchema schema,
string type,
string subType,
string format,
bool upsert ){var tableEntries = new List<DynamicTableEntity>( tableData.Count );
.....
return tableEntries; }
In Some cases it will throw an exception and I would like to test that using Xunit framework. My TDD code is like this:
public async Task UploadAndSchemaCheckOnMissingKey()
{
var table = await _tableStore.PopulateTable(null, lines, schema, "tableOutput", null, "test", false);
await Assert.ThrowsAsync<ArgumentException>(table);
}
I get the error as cannot convert System.Collection.generic.List<table.DynamicEntity> to System.Func<System.Threading.tasks.task>.
How should I handle this that My test case pass when the exception is thrown?
You can use it something like this:
Func<Task> table = async() => await _tableStore.PopulateTable(null, lines, schema, "tableOutput", null, "test", false);
var ex = await Assert.ThrowsAsync<FormatException>(table);
Assert.Contains("expected error message", ex.Message);
