interface TestContextAssert

This function serializes value and writes it to the file specified by path.

test('snapshot test with default serialization', (t) => {
  t.assert.fileSnapshot({ value1: 1, value2: 2 }, './snapshots/snapshot.json');
});

This function differs from context.assert.snapshot() in the following ways:

• The snapshot file path is explicitly provided by the user.
• Each snapshot file is limited to a single snapshot value.
• No additional escaping is performed by the test runner.

These differences allow snapshot files to better support features such as syntax highlighting.

This function implements assertions for snapshot testing.

test('snapshot test with default serialization', (t) => {
  t.assert.snapshot({ value1: 1, value2: 2 });
});

test('snapshot test with custom serialization', (t) => {
  t.assert.snapshot({ value3: 3, value4: 4 }, {
    serializers: [(value) => JSON.stringify(value)]
  });
});
