Test spec

TestSpec must inherit tcframe::BaseTestSpec<ProblemSpec>:

class TestSpec : public BaseTestSpec<ProblemSpec> {};

Except for private helper functions, every member of TestSpec listed below must be protected.

Sample test cases

SampleTestCaseX()

virtual void SampleTestCase1() {}
virtual void SampleTestCase2() {}
// ...
virtual void SampleTestCase25() {}

Defines the sample test cases (up to 25). The following methods are exposed:

---

Subtasks()

void Subtasks(std::set<int> subtaskNumbers);

Assigns the current sample test case to a set of subtasks, if the problem has subtasks. If used, this should be the first call in a sample test case.

Input()

void Input(std::vector<std::string> lines);

Defines the input as exact literal string, given as list of lines.

Output()

void Output(std::vector<std::string> lines);

Defines the input as exact literal string, given as list of lines. It is optional; if not specified, the solution will be run against the sample input to produce the corresponding sample output.

Example

void SampleTestCase1() {
    Input({
        "4 6",
        "a b c"
    });
    Output({
        "10"
    });
}

Test cases and test groups

TestCases()

virtual void TestCases() {}

Defines the test cases.

---

TestGroupX()

virtual void TestGroup1() {}
virtual void TestGroup2() {}
// ...
virtual void TestGroup25() {}

Defines the test cases on each test group (up to 25).

---

Definitions

The following macro is exposed to define test cases:

CASE()

#define CASE(statement, ...)  /* see below */

Defines a test case.

Each statement should be one of:

• assignment to an input variables
• private method call that assigns values to one or more input variables

Example

void TestCases() {
    CASE(N = 42, M = 100, randomArray());
    CASE(N = 1000, M = 1000, randomArray());
    CASE(randomEqualNandM(), randomArray());
}

---

Test case lifecycle

BeforeTestCase(), AfterTestCase()

virtual void BeforeTestCase() {}
virtual void AfterTestCase() {}

Hook up additional logic to run during a test case lifecycle.

For each test case, the following things will happen in order:

1. BeforeTestCase() is executed.
2. The assignments/method calls inside CASE() are executed.
3. AfterTestCase() is executed.
4. Input variable values are printed according to the input format.
