Code Kata: Recently opened files

Kata #2: Recently opened files
Implement a container that has the well known functionality of "Recently opened files" that you know from various applications you use:
  • the container must be able to list file paths that it stores
  • if file A is opened and right after that we ask the container to list the file paths it stores, the path to file A will be listed as the first one
  • the number of stored file paths is limited; when the limit is exceeded the container forgets least recently used file path
  • in the list of recently open files, each file path can appear once and only once

Unit Testing code with IO file operations (in Python)

We may often come across a piece of code that was written without Unit Tests at all. In addition, the piece of code may be dealing with IO like file writing and reading, which makes it more difficult to Unit Test it when we are trying to refactor and modify. Let's suppose the code in question looks like this:

def writeInitialsToFile(filename, name, surname):
    initials = name[0] + '.' + surname[0] + '.'
    with open(filename, 'w') as file:

def readInitials(filename):
    initials = None
    with open(filename, 'r') as file:
        initials = file.readline()
    return initials

A straightforward and bad idea would be to write a couple of Unit Tests that make use of a real file and simply test the reading and writing. Is therea a better way to test this code?

First of all, we need a way to replace the real file with something else. For both reading and writing we will now have a couple of functions, one that expects a stream fo…

Piotr's Less Obvious Advice on Google Mock: State maintenance

Google Mock provides several ways to maintain state inside mock objects. One way of implementing state maintenance is with SaveArg. Consider the following example.

We have a class Configurator, which allows a caller to set and get values of a parameter:

class Configurator

    virtual ~Configurator() {}

    virtual void setParamX(int n) = 0;
    virtual int getParamX() = 0;

And we have a class Client that calls Configurator's methods and it also has a method incParamXBy, that can be used to increase the current value of paramX by a certain value.

class Client

    Client(Configurator & cfg);
    virtual ~Client() {}

    void setParamX(int n);
    void incParamXBy(int n);
    int getParamX();


    Configurator & _cfg;

incParamXBy internally calls setParamX and getParamX on Configurator:

void Client::incParamXBy(int n)
    _cfg.setParamX(_cfg.getParamX() + n);

Let's assume that the initial value of paramX is A and that we want to increase paramX by…

Piotr's Less Obvious Advice on Google Mock: Returning new objects from a mock

Google Mock provides a way to return newly created objects from a mock method. Suppose we have a  Generator class that is supposed to generate new objects when createNewRecord method is called:

class Generator
    virtual ~Generator() {}
    virtual Record * createNewRecord() = 0;

...and suppose we want to mock this class:

class MockGenerator : public Generator
    MOCK_METHOD0(createNewRecord, Record * ());

Suppose the caller class Client has run method defined as follows:

void Client::run()
    for(int i = 0; i < 3; i++)
        rec_tab[i] = gen.createNewRecord();

We want the mock to return a pointer to a new object each time createNewRecord is called. This is how we can express this in the test code:

TEST(ClientTest, CanRun)
    MockGenerator gen;
    Client c(gen);

    EXPECT_CALL(gen, createNewRecord())
                 //this is equivalent of returning new Record(1,2,3)
