I absolutely agree that your insights about your child’s interest and aptitude can never be substituted by any career test’s observations. However, you should also remember that as a parent who has a strong emotional connection with the child and a pre-decided dream about her/his future, you are prone to have some biased opinions that may come in the way of your judgment. 

For example, I have often seen a Mother and a Father of youngsters having very different points of view about their ward’s preferences and career decisions. This difference, you will agree, is a testimonial to the generic tendency of parents to get influenced by emotions while making key decisions about their child’s career. Fortunately, with the evolution of sophisticated psychometric tools, these biases can be easily taken care by utilizing an appropriate psychometric assessment and a counsellor.

Secondly, in case you have any doubts about the accuracy of the report, you always have the option to discuss it with a trustworthy counsellor. Finally, you can also share the career test report with other close relatives who have seen your child grow. Their input is highly insightful and may add tremendous value in this consultative process.

The other point I want to emphasize on is that the recommendation of any reliable career test is never about ruling out or definitively prescribing a specific career path. So you should be alarmed if a psychometric test is providing ready-to-use directions. It may be a disguised test meant for producing pre-decided recommendations. Unregulated institutions often use this trick to admit gullible students and fill classrooms.

I completely agree with you that only a mother / parents can understand the child better. Having said that, the career guidance tests can help parents as a support tool to validate the child's interest vs his intelligence.

As per Howard Gardner, a famous psychologist, human brain learns and interprets the learning in 8 types: 

1. Verbal-Linguistic
2. Logical - Mathematical
3. Visual - Spacial
4. Bodily - Kinesthetic
5. Musical - Rhythmic
6. Interpersonal
7. Intrapersonal
8. Naturalistic

Most of the popular Career Tests are designed to analyze these expertise, from the perspective to understand and analyse:

1. Aptitude - Intelligence
2. Attitude - What motivates us to do / achieve things
3. Personality Type - What have we learned or groomed ourselves to based on our aptitude and attitude

The test reports not only details us about our expertise patterns and interests, but also throws a comparative report about What are the possible career options that people with this combination were successful-in generally.

As parents this can give us a better perspective in deciding or counselling what is good for our child and why? This can be a guided tool which can come handy for parents to take better decisions for our child based on some analysis rather than probably only a gut-feel.

But of course, as you rightly said, who can understand a child better than a mother/parent.
