Empty cells should display the value of a field or property. If a cell contains "blank" or "null" then treat it as blank ("") or truly null.

Empty cells are automatically filled with the value of the field or property, and no check is performed. To explicitly set a value to empty string ("") or null, or to check for empty string or null, use the "blank" and "null" keywords.

This works in column fixtures...

when test is⇓

string fixture
field	field	field?	field?	field?
null		null	blank	joe
blank		null	blank	joe
joe		null	blank	joe

then result is

string fixture
field	field	field?	field?	field?
null	null	null	blank expected null actual	joe expected null actual
blank	blank	null expected actual	blank	joe expected actual
joe	joe	null expected joe actual	blank expected joe actual	joe

...row fixtures...

when test is⇓

blank and null keyword row fixture
field	property	get	field	property	get	field	property	get
null	null	null	blank	blank	blank	Joe	Joe	Joe
blank	blank	blank	Joe	Joe	Joe	null	null	null
Joe	Joe	Joe	null	null	null	blank	blank	blank

then result is

blank and null keyword row fixture
field	property	get	field	property	get	field	property	get
null	null	null	blank expected null actual	blank expected null actual	blank expected null actual	Joe expected null actual	Joe expected null actual	Joe expected null actual
blank	blank	blank	Joe expected actual	Joe expected actual	Joe expected actual	null expected actual	null expected actual	null expected actual
Joe	Joe	Joe	null expected Joe actual	null expected Joe actual	null expected Joe actual	blank expected Joe actual	blank expected Joe actual	blank expected Joe actual

public class BlankAndNullKeywordRowFixture : RowFixture
{
	public override object[] Query()
	{
		StringFixture fixture1 = new StringFixture();
		fixture1.Field = null;
		fixture1.Property = null;
		fixture1.Set(null);
		StringFixture fixture2 = new StringFixture();
		fixture2.Field = "";
		fixture2.Property = "";
		fixture2.Set("");
		StringFixture fixture3 = new StringFixture();
		fixture3.Field = "Joe";
		fixture3.Property = "Joe";
		fixture3.Set("Joe");
		return new object[]{fixture1, fixture2, fixture3};
	}

	public override Type GetTargetClass()
	{
		return typeof(StringFixture);
	}
}

...and action fixtures...

when test is⇓

action fixture
start	string fixture
enter	field	null
check	field
check	field	null
check	field	blank
check	field	Joe

then result is

action fixture
start	string fixture
enter	field	null
check	field	null
check	field	null
check	field	blank expected null actual
check	field	Joe expected null actual

when test is⇓

action fixture
start	string fixture
enter	field	blank
check	field
check	field	null
check	field	blank
check	field	Joe

then result is

action fixture
start	string fixture
enter	field	blank
check	field	blank
check	field	null expected actual
check	field	blank
check	field	Joe expected actual

when test is⇓

action fixture
start	string fixture
enter	field	Joe
check	field
check	field	null
check	field	blank
check	field	Joe

then result is

action fixture
start	string fixture
enter	field	Joe
check	field	Joe
check	field	null expected Joe actual
check	field	blank expected Joe actual
check	field	Joe
