An example of  ColumnFixture, ActionFixture and RowFixture in perl.

 

A null value, i.e. undef, is displayed as “NULL”, but the respective variables contain undef.

In order to achieve this, we use a TypeAdapter, namely the NullFkWrapper.

 

Let’s start with some data (may be the result of a selection on a database...)

 

NullValueTest

id

cname

manager_id

1

busik

NULL

2

berger

1

3

maas

1

4

fieg

NULL

5

tiebe

1

 

NullValueTest is a ColumnFixture, its purpose is solely to take the input data.

 

fit.ActionFixture

start

RowsetFilter

 

 

check

rowCount

0

should be empty on beginning...

enter

findById

1

 

check

rowCount

1

 

enter

findByManagerId

NULL

 

enter

rowCount

2

 

 

Now you’ve seen an ActionFixture in action...

 

How to check, if the system found the right two rows? Let’s check it with a RowFixture

 

FilteredData

id

cname

1

busik

4

fieg

 

You are interested in the cname field only? No problem for a row fixture (and ok, since cname happies to be unique too)

 

FilteredData

cname

busik

fieg

 

What about an empty filtered data?

 

fit.ActionFixture

start

RowsetFilter

 

 

press

clear

 

 

 

FilteredData

id

cname

manager_id

 

Another filter...

 

fit.ActionFixture

start

RowsetFilter

 

 

enter

findByManagerId

1

 

 

FilteredData

id

cname

manager_id

2

berger

1

3

maas

1

5

tiebe

1

 

 

fit.ActionFixture

start

RowsetFilter

 

 

press

allRows

 

 

 

In the output you should see a row marked as “surplus”

FilteredData

id

cname

manager_id

1

busik

NULL

2

berger

1

3

maas

1

4

fieg

NULL
